BEIJING (AP) — A local government’s news site says three assailants with knives rushed into a card room to attack people in China’s western region of Xinjiang, in a clash that drew armed security forces. Two of the attackers were killed and the third one wounded and captured.

The report on the Xinjiang government’s website gave no details on a motive for the Sunday evening attack in Hotan city. It said the civilians fought back and sounded an alarm and that other people came to encircle the attackers. It said armed patrol forces arrived and brought the attackers under control. Four civilians were injured.

The attack came amid a crackdown in Xinjiang following high-profile attacks on civilians. They have been blamed on extremists from the region’s Uighur minority seeking to overthrow Chinese rule.
