Violent street battles killed at least 140 people and injured 828 others in the deadliest ethnic unrest to hit China's western Xinjiang region in decades, and the Chinese government blamed Uighur exiles for stoking the unrest.
Security forces have clamped down on the city of Urumqi and set up checkpoints to catch any fleeing rioters, state media reported, after tensions between ethnic Muslim Uighur people and China's Han majority erupted into riots.
Rioters on Sunday overturned barricades, attacking vehicles and houses, and clashed violently with police, according to media and witness accounts. State television aired footage showing protesters attacking and kicking people on the ground. Other people, who appeared to be Han Chinese, sat dazed with blood pouring down their faces.
