Clashes in the Xinjiang region of China have left more than 20 people dead, including 15 police officers and officials.
The trouble occurred on Tuesday afternoon in Bachu county, Kashgar prefecture.
A statement on the official Xinjiang government website said the incident began when officials searched homes for weapons. Eight people were arrested.
The BBC reports there have been sporadic clashes between the Muslim Uighur and Han Chinese communities in Xinjiang in recent years.
Almost 200 people, mostly Han Chinese, were killed in riots in 2009.
In March, 20 people were jailed on terrorism and separatism charges in the region. Last August courts jailed another 20 people on similar charges in Xinjiang.
