People take part in a candlelight vigil as part of a demonstration in honour of the victims of the mining accident in Soma, on May 16, 2014, at Kadikoy, in Istanbul. Turkish riot police fired tear gas today at thousands of protesters at the scene of a disaster that killed nearly 300 miners, as the government faced a worsening political backlash. Police used tear gas, water cannon and plastic bullets to disperse demonstrators chanting anti-government slogans in the western town of Soma, where at least 284 people died in a blast at a coal mine this week.
