The International Herald Tribune has more details about the most recent attack against police in Xinjiang:
Two police officers who were killed and five who were wounded in an ambush in western China on Aug. 27 were ethnic Uighurs searching for a woman who they thought might have been involved in an earlier attack, said a police officer in the village where the ambush took place.
The attackers were also Uighurs, a Muslim Turkic group common throughout the western region of Xinjiang. Brandishing knives, the attackers set upon a group of unarmed police officers as they were walking through a cornfield in the village of Qizilboy, said the police officer, who spoke on condition of anonymity because he did not have permission to talk to reporters.
The violence against the police suggested that some of the violence in Xinjiang could be aimed at Uighurs seen by other Uighurs as collaborators with the ethnic Han Chinese, who make up the leadership of the Communist Party and govern the region.
