Police in China's northwestern province of Xinjiang have detained some 232 suspects over the past two weeks following recent terrorist attacks in the region.
Media reports in China said on May 12 that the suspects were apprehended in a crackdown on online videos and other Internet content deemed to promote terrorism and religious extremism.
The reports also say new security teams on armored vehicles have begun patrols in the Chinese capital, Beijing.
Armed officers increased patrols across China following a knife attack on May 6 outside the main railway station in the southern city of Guangzhou, which left six people injured.
On March 1, 29 people were killed and 143 injured in knife attacks by several individuals at the main railway station in the southwestern city of Kunming.
Police blamed Xinjiang's indigenous Turkic Muslim Uyghurs for the attacks.
