The death of a 15-year-old boy has set off Turkey’s worst civil unrest in months. Last June, a police tear gas canister hit Berkin Elvan in the head as he walked to buy bread in Istanbul. He then fell into a coma. Since then, Elvan has become a human rights symbol for anti-government protesters. His death on Tuesday sparked peaceful and violent protests across Turkey. The country is gearing up for expected protests today during Elvan’s funeral, and authorities have cordoned off Istanbul’s Taksim Square, the site of last summer’s large anti-government demonstrations.
