Last night checkpoints sealed off the road to the police headquarters where attackers detonated a wagon filled with explosives at 2.30am, killing a civilian guard and injuring two police. According to the Xinhua news agency, the police fired back, killing one of the attackers and capturing two after a fourth killed himself with his bomb. Half an hour earlier, an explosion blew out windows in a row of businesses. The owner of one café, where people were drinking at the time of the explosion, said: “Suddenly there was a big bang. The customers and I just ran away. When I looked back, my shop was totally destroyed.”
At 8.30am, police cornered five of the alleged attackers under a market stall. Two were shot dead as they threw their bombs while the other three blew themselves up. There were also attacks on a local government building and the premises of a trade organisation. A curfew was imposed and businesses in Kuqa county were ordered to close as police hunted for attackers, who, said Xinhua, had used bombs made from pipes, gas canisters and containers of liquid gas.
