Thirteen assailants have been killed in an attack on a police station in China's restive western province of Xinjiang, officials say.

The attackers drove a car into the station and set off explosives on Saturday morning, the local government said on its website.

Three police suffered minor injuries but no civilians were hurt, it added.

The Chinese authorities blame Muslim Uighurs from Xinjiang for an increasing number of attacks in the province.

"On the morning of 21 June, a group of thugs drove a car into a police building in Yecheng County, Kashgar province and detonated explosives," the local government website said.

The case was currently under investigation, it added. It provided no further details.

Verifying reports from the Xinjiang region is difficult because the flow of information is tightly controlled.

On Monday, China executed 13 people in the western province of Xinjiang for what it called "terrorist attacks".

The authorities also sentenced three men over a fatal car crash in Beijing last year.
