Boston bombing: LIVE UPDATES

The second suspect behind the Boston Marathon bombing, Dzhokhar Tsarnaev, has been arrested following an extensive manhunt that ended in the Boston suburb of Watertown. His brother Tamerlan was pronounced dead by law enforcement early Friday.

April 26

19:09 GMT: The parents of the Tsarnaev brothers, Anzor and Zubeidat, have left their home town of Makhachkala for Moscow from where they plan to take a flight to the US in order to meet with their son, Dzhokhar, RIA-Novosti reports.

18:59GMT: US intelligence agencies added the mother of the Boston bombing suspects, Zubeidat Tsarnaeva, to a federal terrorism database, TIDE, about 18 months before the attack occurred, AP cites two unnamed government officials.

April 24


23:55 GMT:In a direct contradiction to Boston Police Commissioner Ed Davis, who had stated that shots were fired from inside the boat where Dzhokhar Tsarnaev was apprehended, officials disclosed to the AP that he was unarmed at the time of arrest.

23:30 GMT: Federal investigators have disclosed that the homemade, pressure-cooker bombs were triggered by a remote detonator, the AP reports. The “close-controlled” devices are described as the sort used in remote-controlled toys. According to one US official, the suspects would have had to be several blocks in proximity to the explosives to detonate them.

The AP also reports that Russian officials approached the CIA months after the FBI had cleared Tamerlan Tsarnaev in an investigation into possible terrorist ties. The CIA then added the suspect's name into its massive Terrorist Identities Datamart Environment database. Russia’s initial warning to the FBI was shared in March 2011.

20:20 GMT: American authorities have informed the suspects’ family that they may now access older brother Tamerlan's body for burial, though an uncle’s request to a Boston-area mosque for a funeral was denied, according to their aunt Patimat Suleimanova.

The mosque, which is run by the Islamic Society of Boston, did not respond to a request by NBC News, though the group did say that its congregants had been questioned by the FBI. Tamerlan Tsarnaev had attended and occasionally caused disruptions at the mosque, after which he was threatened with ejection.

18:50 GMT: The Boston Marathon explosions were triggered by a remote-controlled detonator, AP quotes the US officials close to the ongoing investigation as saying, adding that the bombs were not very sophisticated. One of the officials described the detonator as "close-controlled" — meaning it had to be triggered within several blocks of the bombs. It was not immediately clear what the detonation device was. A criminal complaint outlining federal charges against the only surviving suspect, Dzhokhar Tsarnaev, described him as holding a cellphone in his hand moments before the first explosion.

April 23

20:15 GMT: Katherine Russell, the wife of slain suspect Tamerlan Tsarnaev and the mother of his child, has released a statement through her attorney, Amato DeLuca:

Our firm is representing Katherine Russell and she has asked us to make a short statement. As you know from news reports, Katie married her husband in June of 2010. Since then, she has been living in Cambridge, raising her child and working long hours, caring for people in their homes who are unable to care for themselves. Katie grew up in Rhode Island and has always remained close to her parents and sisters here, as well as her extended family. She is fortunate to have the support of her loving family now, as they, too, struggle to come to terms with these events and the deep sorrow we all feel following the events of last week. Meanwhile, she is doing everything she can to assist with the investigation.

The injuries and loss of life — to people who came to celebrate a race and a holiday — has caused profound distress and sorrow to Katie and her family. The reports of involvement by her husband and brother-in-law came as an absolute shock to them all. As a mother, a sister, a daughter, a wife, Katie deeply mourns the pain and loss to innocent victims — students, law enforcement, families and our community. In the aftermath of this tragedy, she, her daughter and her family are trying to come to terms with these events.

Thank you.

19:32 GMT: Homeland Security Secretary Janet Napolitano told a Senate Judiciary panel that an immigration bill currently making its way through congress could fix border control weaknesses which might have facilitated last week’s Boston Marathon bombings.

"The bill will help with this because it requires that passports be electronically readable as opposed to having manual input," Napolitano testified, adding the legislation "really does a good job of getting human error out of the process."

Previously, Republican Senator Lindsey Graham revealed that a misspelling of Tamerlan Tsarnaev's name on flight records when departing the United States for Russia last year may have allowed him to avoid detection from authorities. Tsarnaev had been put into the Treasury Enforcement Communications System, which helps US officials screen individuals arriving to the country, following a 2011 interview with the FBI.

18:23 GMT: Lawyers for Katherine Tsarnaeva, widow of the slain Boston bombings suspect Tamerlan Tsarnaev, have said that she is doing everything she can to assist authorities. Tsarnaeva said it had come as an absolutely shock to her that either her husband or brother-in-law had played any role in last week’s deadly blast. Her lawyers continued that she is “trying to come to terms with these events.” It remains unclear to what extent she has helped authorities, as her attorneys would not comment on whether she had already spoken with federal investigators.

17:36 GMT: Eight-year-old Martin Richard, the youngest victim in the Boston Marathon bombings, was laid to rest during a private funeral on Wednesday morning.

"We laid our son Martin to rest, and he is now at peace. We plan to have a public memorial service in the coming weeks to allow friends and loved ones from our community to join us for a celebration of Martin’s life," WCVB Boston cites a statement by the family as saying.

The Richard’s family thanked the outpouring of “love and support” they had received over the last week. They further expressed their faith that the criminal justice system will now “do its job” following the arrest of Dzhokhar Tsarnaev on Friday night.

Martin’s mother and sister were among those injured in the dual blasts.

17:00 GMT: The surviving Boston Marathon bombings suspect, Dzhokhar Tsarnaev, told interrogators that US-led wars in Iraq and Afghanistan had motivated him and his brother to carry out last week’s deadly assault, The Washington Post cites US officials as saying on condition of anonymity.

The 19-year-old suspect, who is currently hospitalized and in fair condition, further acknowledged his role in planting the explosives near the Boston Marathon finish line last week.

The officials, who believe the brothers acted alone in carrying out the attack, believe the pair had been “self-radicalized” as a result of US actions in the Muslim world and information found on the Internet.

16:40 GMT:


01:54 GMT: Dzhokhar Tsarnaev, the surviving suspect in the Boston Marathon bombings, told investigators that his brother Tamerlan had organized and led the attack that left three people dead and scores injured last week, a US government source told CNN. 

Tsarnaev met with investigators from his hospital bed Monday, telling them he and his brother worked alone and were motivated by a drive to "defend" Islam from a US attack. Tsarnaev, who is unable to speak because of a gunshot wound in his neck, and his brother also fit the description of lone-wolf jihadists who worked without the backing of a major terror network, the source said.

23:51 GMT: Tamerlan Tsarnaev was known to have argued with and lashed out at a preacher in a local mosque, the Associated Press reports. Before Thanksgiving in November 2012, Tamerlan argued with a preacher who said it was appropriate for Muslims to celebrate some American holidays. This January, he called the preacher a “hypocrite” who was “contaminating people's minds” during a sermon that included praise for Martin Luther King Jr.

22:42 GMT:  Evidence from the first interrogation suggests the suspects in the Boston Marathon attack were “motivated by religion” but had no ties to Islamist terror groups, two US officials told the Associated Press on condition of anonymity. While the Tsarnaev brothers - like many Chechens - practiced Islam and appeared to have a strong sense of ethnic identity, the two had only spent a small and early portion of their lives in their homeland. Both were ethnic Chechens, but Dzhokhar Tsarnaev was born in Kyrgyzstan while brother Tamerlan was born in the Russian republic of Kalmykia. By the time of the Boston attack, both brothers had been living in the United States for over a decade.

22:28 GMT: Boston bombing suspect Dzhokhar Tsarnaev has been read his Miranda rights by a US judge during a bedside hearing in the Beth Israel Deaconess Medical Center.

22:07 GMT: The owner of the car hijacked by the two Boston Marathon bombing suspects claims that one of them admitted to carrying out the blasts. “Did you hear about the Boston explosion? I did that,” one of the suspects asked the victim according to a report obtained by The Wall Street Journal. “I am serious,” he added showing the bullet inside his gun’s magazine.

22:01 GMT: A 7-year-old girl remains hospitalized in critical condition with “multiple leg injuries” along with several dozen others who suffered injuries in the Boston Marathon blasts. The Children's Hospital of Boston declined to identify the girl.

21:13 GMT: The first victim of the blast Krystle Campbell, 29, was laid to rest at a private ceremony at St. Joseph's Church in Medford.

18:45 GMT: People in Boston and other cities are observing a moment of silence for the victims of the Boston Marathon bombing, a week after the explosions that killed 3 people and injured more 170 on April 15.

18:44 GMT: Tsarnaev agreed to a probable cause hearing scheduled for May 30, according to the Department of Justice.

18:10 GMT: The 19 year-old Dzhokhar has been charged with using weapons of mass destruction, a federal crime which is punishable by death, life in prison, or any other indeterminate prison sentence, the Justice Department said. In addition to that he has been charged with malicious destruction of property resulting in death.

17:31 GMT: The White House said that Dzhokhar Tsarnaev, the surviving suspect will not be tried as an enemy combatant in a military tribunal. Tsarnaev will be prosecuted in the federal court system as under US law the country’s citizens cannot be tried in military commissions, said Jay Carney, a White House spokesman. He added that President Barack Obama's entire national security team supports the decision.

17:30 GMT: Federal prosecutors charged Tsarnaev while he still remains in a hospital bed in serious condition. "There has been a sealed complaint filed," said Gary Wente, circuit executive for the U.S. Courts for the First Circuit.

16:45 GMT: A misspelling in Tamerlan Tsarnaev’s name kept the FBI in the dark about the slain suspect’s early 2012 trip to Russia, US Senator Lindsey Graham said.

“He went over to Russia, but apparently, when he got on the Aeroflot plane, they misspelled his name,” Graham, a South Carolina Republican said on Fox television this morning. “So it never went into the system that he actually went to Russia.”

Graham continued that it remained unclear whether Tsarnaev had intentionally misspelled his name in order to cover up his tracks.

16:45 GMT:

Recovering from the Boston Marathon bombings will psychologically be

“a marathon”, Dr Terence Keane, a psychiatrist at the Boston Medical Center where many of the injured are being treated, said.

Stating it might take months for people to get back to normal, Keane urged people to “limit exposure to the media” and “establish normalcy.”

"For many people it will be difficult to get back into the normal routine. You may not feel like it, you may not be energized to do this, yet from a set of long-standing scientific studies, the people that do best are the people that get back to normal," Dr Keane said.

16:38 GMT: Dzhokhar Tsarnaev, the surviving suspect in the Boston Marathon bombings, is answering brief questions by nodding his head, a source close to the investigation told CNN on Monday. The source said investigators have questioned Tsarnaev on whether there were more bombs, explosives, weapons caches, or if anyone had helped him and his brother carry out last Monday’s attack. It was not immediately clear what information the suspect, who is currently restrained and on a ventilator, has provided. The source continued that investigators are questioning Tsarnaev every few hours in the presence of doctors.

15:00 GMT: Forty eight people injured in last Monday's attack  are continuing to receive inpatient medical treatment, while two remain in critical condition. On Sunday it was reported that fifty two people remained hospitalized, while three were in critical condition. 

13:45 GMT: Boston Medical Center's doctors: "It will take months for the victims of the bombing to recover".

13:37 GMT:

10:50 GMT: The FBI is disputing a claim by the mother of the suspected Boston bombers, who said the bureau had spoken to the older brother after the bombs exploded at last Monday's marathon. At FBI headquarters in Washington, spokesman Michael Kortan says the bureau's 2011 interview with Tamerlan Tsarnaev was the only FBI contact with him. Kortan is standing by the bureau's public statement from Friday in which the bureau described that interview. That statement says the FBI did not learn of the identities of the bombing suspects, Tamerlan and his brother, Dzhokhar, until Friday, the day Tamerlan was killed. The brothers' parents in Russia have insisted that the FBI continued to monitor Tamerlan after the 2011 interview and say both of their sons were set up.

09:19 GMT: Dzhokhar Tsarnaev remains in a serious condition, reports the FBI at the request of Beth Israel Deaconess Medical Center, where the suspect is being treated.

4:14 GMT: As investigators are struggling to understand the motives behind the deadly Boston bombing, RT spoke to a relative of the suspected attackers who stressed that the elder of Tsarnaev brothers, Tamerlan, was not a religious fanatic.

Tamerlan wasn’t a religious fanatic," she told RT’s Madina Kochenova. “He was curious about religion. He started to be really interested in Islam about three years ago,  but he was never a radical. We would talk about his commitment to religion, but it wasn’t extreme.”

3:45 GMT: FBI asked Tamerlan Tsarnaev's wife's lawyer if they could speak with her, but he informed them of her refusal.

On Sunday, the authorities visited the home of Tsarnaev's in-laws, where Katherine Russell Tsarnaev is currently staying - according to lawyer Amato DeLuca's statement to AP. Having gotten a refusal, they are now discussing how to proceed.

Russell-Tsarnaev has been saying that she never suspected Tamerlan of anything and that nothing prompted her to think he was behaving suspiciously even after the bombings.

Tamerlan would normally stay at home to take care of their daughter while Katherine was away working. Her lawyer says Tsarnaev was home on the day of Tamerlan's death, as his wife had left for work.

3:00 GMT: The Tsarnaev brothers were allegedly planning to head to New York, having hijacked their Mercedez-Benz getaway car and told the hostage driver of their intentions. That is according to a New York Times' conversation with a US official.

This adds to the already existing suspicion by the FBI that the bombing suspects had been planning to kill more people.

1:40 GMT: Dzhokhar Tsarnaev answers questions in writing, as he is asked by police about possible accomplices and other potential unexploded devices - according to tweets from ABC news network.

1:05 GMT: The Tsarnaev brothers were not licensed to carry firearms in the towns where they lived, said police spokesman Dan Riviello.

"There is no record of him having a license to carry," Reuters cited Riviello.

RT's Anastasia Churkina with the latest developments from Boston:


23:28 GMT: The Boston Marathon bombing suspect Dzhokhar Tsarnaev is awake and is being questioned by authorities, ABC News reports. This comes after officials said that the alleged bomber was in serious condition and unable to communicate verbally due to a throat injury.

He is being treated at Beth Israel Deaconess Medical Center in Boston.

21:30 GMT:  Senior members of the US Congress have criticized the FBI for "dropping the ball" on a promising lead back in 2011, when they got word from the Russian government that Tamerlan Tsarnaev is a person of interest and should be interviewed. Michael McCaul, who is the Republican chair of the House homeland security committee, has asked the FBI to provide answers.

"He was interviewed by the FBI in 2011 and let go. He travelled back to Russia and spent six months there," McCaul told CNN.

Apparently, the FBI never followed up the inverview, but claimed they had found nothing suspicious about Tamerlan at the time, saying on Friday that they "did not find any terrorism activity, domestic or foreign", relating to the older brother's travel records. They declined to give further comments.

 A Republican senator, meanwhile, was quoted by CNN as saying to the committee that "the FBI missed a lot of things is one potential answer, or laws do not allow the FBI to follow up in a sound, solid way."

20:53 GMT:


20:38 GMT: Terminal 4 at JFK International Airport in New York City has been fully evacuated after a suspicious package was discovered on Sunday. A source at JFK told WABC news channel that the package was being boarded on to a plane. Bomb squad has arrived at the scene. There have been numerous reports of suspicious unattended objects across the US in the wake of the Boston Marathon bombing.

19:45 GMT: Fifty two victims of the Boston Marathon bombings are continuing to receive inpatient medical treatment, while three remain in critical condition. Three people were killed and more than 180 were injured in Monday’s attack.

18:04 GMT: The FBI’s facial-recognition software failed to identify the suspects on the video taken before the bombing, even though the images of both existed in official databases, Boston police commissioner Edward Davis told The Washington Post. The Tsarnaev brothers could have been found in multiple databases, as both had legally immigrated, while Dzhokhar had a driver’s license, and Tamerlan had been the subject of an FBI investigation.

17:27 GMT: Members of six churches gathered to honor the Boston bombings’ victims at an interfaith memorial service on Sunday. A wake for the bombing victim Krystle Campbell is also being held Sunday at a funeral home in Medford.

16:31 GMT:

15:12 GMT: The bombing suspects killed Officer Sean Collier, 26, of the Massachusetts Institute of Technology campus police on Thursday, said Boston's police commissioner. 

"Tragically, Officer Collier from the MIT police was murdered by these individuals as they started their rampage," said Commissioner Edward Davis on Fox News Sunday.

He added that they had other explosives that the authorities detonated. The authorities believe the suspects intended to use them. "We feel that they had plans to use those explosives, possibly on soft targets," Davis said.

15:10 GMT: Boston’s police commissioner, Edward Davis, says Tsarnaev is still in a serious condition in hospital and authorities have still not been able to question him. He also said that based on the evidence at the scene and the firepower both brothers had in their possession; it was his belief that they “were going to attack other individuals”.

15:05 GMT: US authorities have not yet read Dzhokhar Tsarnaev his Miranda rights. This means that Tsarnaev will not be advised of his right to remain silent or his right to counsel before he is questioned. This is known as a public safety exception to Miranda and will be an important test case of civil liberties and the US legal system.

13:36 GMT:


13:35 GMT: Dzhokhar Tsarnaev, the Boston bombing suspect, remains unable to speak as he undergoes treatment for a gunshot wound to his throat. CBS television quoted investigators as saying that he had lost a lot of blood and one wound in the back of his neck could have been a suicide attempt.

13:28 GMT:

A statement released on a website used by Russian North Caucasus rebel groups has denied any link to the Boston Marathon bombings.

"The command of the Vilayat Dagestan mujaheddin... declares that the Caucasus fighters are not waging any military activities against the United States of America. We are only fighting Russia," the Kavkazcenter.com website said in a statement.

12:57 GMT: Two alleged friends of Dzhokhar Tsarnaev, owners of a BMW with a license plate “Terrorista #1”, were taken to custody in New Bedford, Massachusetts, on Saturday on charges of violating immigration law, the Daily Mail reports. Both are students, presumed to come from Kazakhstan. Neighbors say their names are Azmat and Diaz. Police say the surviving suspect behind the Boston bombings might have lived with them. The two were first arrested on Friday, but soon released. The Saturday arrest might end up in their deportation.

12:26 GMT: The family of a missing student falsely named as one of the Boston terror suspects were bombarded with hate messages. Sunil Tripathi, a 22 year old philosophy student was falsely identified as one of the suspects on Twitter as photographs of the two wanted men were released by police. His name was circulated among millions of people on social networking sites amid rumors that his name has been over heard on police radio scanners. The fact that he had been missing for a month was cited as corroboration.

Eventually Officials from the FBI were forced to name the real suspects, earlier than they had planned.

07:22 GMT: Runners in the London Marathon are being asked to wear black ribbons during the race as a mark of respect for those who died in Boston, reports the BBC.

05:01 GMT: An infrared video was released by the Boston police revealing the hiding place of Dzhokhar Tsarnaev in a boat in the backyard of a house in the Boston suburb of Watertown.

04:54 GMT: The London Metropolitan Police have deployed hundreds of extra officers to beef up security at today’s London Marathon. Chief Superintendent Julia Pendry said the extra officers would be used for so-called “reassurance patrols.”

"There is no link between the Boston Marathon and the London Marathon and there is no change to the threat level at this time to London," she told the BBC. She added search dogs would be used at the event and urged spectators to keep their belongings with them at all times to avoid sparking a security alert. As a mark of respect for the three people that died and the 170 injured in the bomb blasts in the Boston Marathon on Monday, a 30-second period of silence will be held at the beginning of the race.

01:18 GMT:  The Tsarnaev brothers used their carjacking victim's ATM card before a gunfight with authorities, police say. Watertown Police Chief Edward Deveau says the suspects behind the Boston Marathon bombing also told the carjacking victim they bombed Monday's race and killed a police officer.


00:25 GMT:  Dzhokhar Tsarnaev, the suspect behind the Boston Marathon bombing who was arrested on Friday night, suffered a throat injury and may not be able to talk, a federal official told CNN on condition of anonymity. Earlier Massachusetts Gov. Deval Patrick said that Tsarnaev was in a "serious but stable condition" adding that he was "not able to communicate yet."


April 21

23:30 GMT: Dr. David Schoenfeld, who was involved in treating the older of the two bombing suspects - 26-year-old old Tamerlan Tsarnaev, said that the man had been so riddled with gunshot wounds on arrival to the hospital that it was impossible to determine which wound had been fatal. The doctor added that if Tsarnaev had been wearing a vest with explosives, he wasn't anymore, upon arrival to the hospital.


20:50 GMT:

18:27 GMT: The Federal public defender’s office in Boston says it is seeking to represent surviving Boston marathon bombing suspect Dzhokhar Tsarnaev, Reuters reports. Earlier in the day, top Republican senators had requested that Tsarnaev be held as an enemy combatant, a status which would deny him the right to a government appointed attorney and other legal protections.

18:17 GMT: Russia asked the FBI to investigate Boston Bombing suspect Tamerlan Tsarnaev in 2011, a US law enforcement source told Reuters. The FBI had previously reported on its website that an unidentified ‘foreign government’ had inquired about the slain suspects radical Islamist views, further requesting that they agency investigate his links with certain terrorist groups. The FBI says they found nothing suspicious at the time.

18:03 GMT: Top Republican senators urged US President Barack Obama to hold the suspect of  marathon bombing Tsarnaev as a potential enemy combatant, US media report. That status will deny him a government-appointed attorney and other legal rights in an attempt for the investigators to learn about other possible attacks.

“The suspect, based upon his actions, clearly is a good candidate for enemy combatant status. We do not want this suspect to remain silent,” said senators  Lindsey Graham, South Carolina; John McCain, Arizona; and Kelly Ayotte, New Hampshire as cited by the New York Daily News.

17:01 GMT: The FBI asked the Beth Israel Deaconess Medical Center personnel not to give any updates on the condition of the suspect Dzhokhar Tsarnaev, ABC News has reported citing a hospital spokesperson. As of early morning Boston time, the suspect was still alive, the report added.

16:45 GMT: Friends of the Boston bombing victim Jeff Bauman, who lost both his legs below the knee, have set up an online fundraiser to help him pay for the hospital bills. Bauman was “severely affected” by the blast after an explosive devise detonated right next to where he stood watching the marathon. Despite his serious condition, Bauman managed to describe the suspect, who later turned out to be of the Tsarnaev brothers, immediately upon gaining consciousness in intensive care. Nearly $350,000 has already been collected for Bauman in what his friends called “amazing” public support they were “truly blessed to have.”


16:09 GMT: The suspects in the Boston Marathon bombings likely acted alone, according to early indications, the Watertown, Massachusetts, police chief Edward Deveau told CNN on Saturday.

14:44 GMT: North Korea denied that it has any links to the Boston Marathon bombing, saying it “maintains a stance against any form of terrorism,” as quoted by the KCNA. The statement also said North Korea will not hide behind terrorism if it ever feels the need to strike the US, dismissing the allegations posted on the American news website WND that the country might be behind the bombing as an attempt by “hostile forces” to damage its reputation.

12:37 GMT: Russian intelligence services have contacted their American colleagues. They indicated that, “the Tsarnaev brothers didn’t live in Russia, so our service couldn’t provide any information significant for the operation for our foreign partners.”

10:12 GMT: Interpol has notified 190 countries of the nature of explosive devices used by the Tsarnaev brothers, as well as provided data on the suspects. The ‘orange notification’ was issued on US law enforcement authorities’ request.

08:13 GMT: Massachusetts police have found seven explosive devices, allegedly made by the Tsarnaev brothers, NBC news reported. The devices were discovered in Dzhokhar Tsarnaev’s flat in the town of Cambridge, and in Watertown.

07:25 GMT: One of the brothers suspected of the Boston bombings, Tamerlan Tsarnaev, faced deportation in 2009 after being convicted of domestic violence. However, he was allowed to stay, government watchdog Judicial Watch indicated.

06:35 GMT: Law enforcement officials in Dagestan, the region where the two brothers come from, are not conducting any investigation over the fact that the suspects lived there for some time.

“There are no reasons for us to look into the Tsarnaev family at the moment,” a spokesperson said.

06:26 GMT: Presidents Putin and Obama spoke on the phone following the deadly Boston bombings and the manhunt for suspects, who turned out to be ethnically from the Russian republic of Chechnya. The American leader thanked Putin for his condolences expressed to the US people, with the two presidents agreeing to continue cooperating on counterterrorism and security issues.

06:07 GMT: The FBI reportedly interviewed the eldest of the brother suspects in 2011. Tamerlan Tsarnaev did not produce any "derogatory" information back then, according to a source quoted by Reuters.

05:12 GMT: A doctor who attended Tamerlan Tsarnaev when he got to the hospital provided his account of the events. When Tsarnaev arrived, he immediately went into cardiac arrest. CPR was performed until a team of doctors could attempt to resuscitate him, inserting chest tubes to treat potential injuries. However, Tsarnaev sustained massive, penetrating injuries, and was pronounced dead at 1.35am. His body was then taken by law enforcement officials to be examined by forensics, The Huffington Post indicated.

02:24 GMT: US President Barack Obama, summing up what has “all in all been a tough week” for Americans, thanked Bostonians for their perseverance in the wake of the marathon bombings and said “whatever hateful agenda” the terrorists had “will not, cannot prevail.”

Obama said law enforcement worked “as they should” throughout the week-long manhunt, but was careful to stress that the investigation is not over.

“Why did young men who grew up and studied here … resort to such violence?” the president wondered. “How did they plan and carry out such attacks – and did they receive any help?”

Obama also reminded the country of the fertilizer plant explosion earlier this week in West, Texas, where 14 people have been killed and others remain missing. The blast “leveled” four blocks of homes, but President Obama pledged federal aid to the region, along with his sympathy.

02:09 GMT: Federal and local law enforcement officials were visibly excited Friday night when they appeared in front of international media with updates on the capture of Dzhokhar Tsarnaev arrest. State Police Col. Timothy Alben, just hours after stating that investigators had no update on the suspect's location, said Tsarnaev was taken into custody after exchanging gunfire with police.

“We’re exhausted folks, but we have a victory here tonight,” he said.
 
Boston Police Commissioner Ed Davis said that it was a major priority to apprehend Tsarnaev alive, in part to send a message to the rest of the world that due process is a priority in the United States.

“We always want to take all of the suspects alive so that we can find out what happened, why it happened, and take them in for justice,” Davis said.  

US Attorney Carmen Ortiz, after dodging a question about whether arresting officers administered Tsarnaev his Miranda rights, would not answer if they’d seek a federal death penalty, citing an “ongoing investigation.”
