He had been in a coma for 269 days.The protesters had initially been angered by plans to raze Gezi Park and redevelop it but the police crackdown galvanised anti-government demonstrators in several cities.Berkin Elvan was 14 when he was hit on the head by the tear gas canister in the Istanbul neighbourhood of Okmeydan. He was one of thousands of people hurt during the protests.His health had deteriorated in recent weeks and doctors said his weight had dropped to 16kg (35lb).Of the eight protesters whose deaths were related to the demonstrations, one was a police officer.After the boy's death was announced, his mother appeared outside outside Okmeydani hospital and was quickly surrounded by mourners. Tributes appeared on social media in Turkey and a crowd gathered.Riot police arrived at the scene and protesters attacked one of their vehicles. Journalists at the scene say police responded by firing pepper spray at the crowd.Further demonstrations are expected later in Istanbul and the capital, Ankara.
