Protesters clashed with police in cities across Turkey on Tuesday after the death of a 15-year-old boy who was hit in the head by a tear-gas canister during anti-government demonstrations last summer.
Berkin Elvan, then 14, got caught up in street battles in Istanbul between police and protesters on June 16 while going to buy bread for his family. He slipped into a coma and became a rallying point for government opponents, who held regular vigils at the hospital where he lay in intensive care.
