BEIJING (AP) — Chinese state media say police in the restive western region of Xinjiang shot dead an armed assailant for attacking a police officer, who later died.

The official China News Service said Wednesday the suspect used unspecified weapons to injure a police officer in the city of Urumqi on Monday night. Officers who arrived at the site shot the attacker dead.

The injured officer later died. He was 29.

The report did not identify the ethnicity of the assailant, but it was the latest in a series of attacks pointing to growing unrest in the sprawling region.

Xinjiang is home to a simmering rebellion against Chinese rule among parts of the native Turkic Uighur (pronounced WEE’-gur) population who chafe against Beijing’s rule.
