Turkey tear gas

Sami and Gülsüm Elvan hold up a photograph of their son, Berkin Elvan. 15-year-old Berkin died on March 11, 2014 after 269 days in a coma. The Istanbul schoolboy incurred a head injury that doctors say was most likely inflicted by police shooting a teargas canister directly at him at close range. © 2013 Ole Solvang/Human Rights Watch
