Suspected organizer of Moscow Metro blast killed
Magomedali Vagabov is believed to have been a leader of one of the militant groups in Russia's Southern Republic of Dagestan.
He was on the federal and international wanted list for over two years.
Vagabov is thought to have had close links to the suicide bomber Maryam Sharipova, who blew herself up at Moscow's Lubyanka Metro station. A second female bomber detonated her suicide belt at Park Kultury Metro station. The twin blasts killed 40 people and injured more than a hundred.
