Chinese police shot and killed 14 people during a riot near the old Silk Road city of Kashgar in which two policemen were also killed, the regional government said on Monday, in the latest incident of unrest in the far western region.
Police were attacked by a mob throwing explosive devices and wielding knives on Sunday when they went to arrest "criminal suspects" in a village near Kashgar in Xinjiang province, the government said on its official news portal Tianshan (www.ts.cn).
"Police responded decisively," the government said in a brief statement, adding that two people had also been detained and that an investigation had been launched.
Reuters was unable to immediately reach government officials for comment.
At least nine civilians and two policemen were killed when a group of people armed with axes and knives attacked a police station also near Kashgar last month, state media has said.
China called the crash an attack carried out by Islamist militants from Xinjiang plotting holy war, and has reacted angrily to suggestions that it was because of frustration and anger over government repression of the region's Muslims.
Many of Xinjiang's Turkic-speaking, Muslim people chafe at restrictions on their culture, language and religion, although the government insists it grants them broad freedoms.
Xinjiang has been the scene of numerous incidents of unrest in recent years, which Beijing often blames on the separatist East Turkestan Islamic Movement, even though many experts and rights groups cast doubt on its existence as a cohesive group.
