Police patrol shot at in central Istanbul - reports
The incident happened in the city’s Beyoglu district.
The injured officer was taken to hospital. He is said to have sustained a gunshot wound to his arm, but the injury is not life threatening.
Police sent reinforcements to the area to track the perpetrators, who had fled.
In late-December, a blast at Istanbul’s Sabiha Gokcen Airport killed one person, injured another and damaged five planes.
The attack, carried out with mortar bombs, was claimed by a Kurdish armed group.
Earlier, the city had seen hundreds taking part in protests against Ankara’s security operations and curfews in the southeastern – mainly Kurdish – areas of Turkey.
Turkish forces have killed nearly 300 Kurdish fighters since the ceasefire between the government and Kurdistan Workers’ Party (PKK) collapsed in July 2015.
