Assailants attacked police and other people with knives and set fire to police cars in China's restive far-western region on Wednesday in violence that killed 27 people, one of the bloodiest incidents since unrest in the regional capital killed nearly 200 in 2009, AP reported. The early-morning violence - described by state media as riots - also left at least three people injured in a remote area in Xinjiang region, the official Xinhua News Agency said. Police stations, a government building and a construction site were targeted in the attacks, it said. Xinhua said the attackers stabbed victims and set fires, killing 17 people including nine police or security officials, before officers shot and killed 10 of the assailants in Lukqun, a township in Turpan prefecture. The agency cited officials with the region's Communist Party committee.
