The Chinese authorities say more than 140 people died and hundreds more were wounded in riots in the mainly Muslim region of Xinjiang.
Several hundred people were arrested after protests on Sunday turned violent.
Beijing says Uighurs went on the rampage but one exiled Uighur leader says police fired on students.
The protest was reportedly prompted by a deadly fight between Uighurs and Han Chinese in southern China last month.
