BEIJING  Trials may begin this week for more than 200 people charged with crimes after riots last month in China’s far-western Xinjiang region, the state-run newspaper China Daily reported on Monday.

China Daily, an English-language newspaper, quoted an unnamed police source as saying security had already been ratcheted up for the trials, which would be held in the Intermediate People’s Court in Urumqi, Xinjiang’s capital, site of the riots.

The charges include vandalizing public property, inciting crowds to cause bodily harm, murder, arson and robbery, the newspaper said. Investigators were reported to have assembled more than 3,300 pieces of evidence for the trials, including video clips, photographs and bloodied weapons.

At least 197 people died and 1,600 were injured during several days of violence that began July 5 after Uighurs took to the streets to protest the treatment of Uighur factory workers involved in a dispute in southeastern China. The rioters lashed out at Han Chinese, China’s dominant ethnic group, who made up most of the dead and injured. Gangs of Han took revenge on Uighurs in the last days of the violence.
