The students march for Berkin Elvan, a Turkish teenager who died Wednesday, after being in a coma for nine months after being hit on the head by a tear gas canister fired by police during the summer’s anti-government protests in Istanbul, in Ankara, Turkey, Friday, March 14, 2014. The protesters called for Prime Minister Recep Tayyip Erdogan to resign. Elvan, who turned 15 in January, was caught up in the protests on his way to a shop to buy bread. (AP Photo/Burhan Ozbilici)
