Protesters are hit by water cannon during clashes with riot police in Kadikoy, on the Anatolian side of Istanbul, on March 11, 2014. Turkish riot police fired tear gas Tuesday at protesters massed outside a hospital after the death of a teenage boy wounded during anti-government protests last year and left comatose. About 1,000 people staged a rally outside an Istanbul hospital in solidarity with 15-year-old Berkin Elvan, who was walking to buy bread when he was struck in the head by a tear gas canister during the unrest in the city in June.
