BEIJING (AFP) - Knife-wielding attackers killed 10 people in China's Xinjiang region and another four were shot dead by police as a wave of violence swept the ethnically-torn area, state media and officials said Sunday. The unrest occurred in the ancient Silk Road city of Kashgar in two separate attacks, and local residents said Sunday the city centre was under lockdown, with security forces patrolling the streets. Earlier this month, more than 20 people were killed in a clash with police in the remote city of Hotan. In the first attack on Saturday evening, seven people were killed and 28 others hurt at a night market by two attackers with knives, one of whom was later killed in violence, the authorities said. Hou Hanmin, spokeswoman for the government of the northwestern region, told AFP the attackers were both Uighurs.
