The attack occurred around 9 a.m. as local government officials were checking the names of people passing through a checkpoint about 18 miles from Kashgar, the oasis town where 16 paramilitary border guards were killed in an attack on Aug. 4. In a separate incident, assailants detonated explosives and clashed with police in the Xinjiang town of Kucha on Sunday; 10 attackers, one security guard and one bystander died, according to state media reports.
The spike in violence has claimed 31 lives in the restive desert region where China meets central Asia. It comes after a separatist group that calls itself the Turkestan Islamic Party released three videos threatening attacks during the Olympic Games, especially targeted at government and police facilities and key Olympic areas. Chinese government officials say they have no evidence the attacks are linked to separatist groups, but they have suggested the attacks are terrorism.
