Chinese officials say police have shot and killed two Muslim Uighurs and injured another in renewed violence in northwestern Xinjiang province.

The state-run Xinhua news agency says police opened fire Monday to stop the three from attacking another Uighur with clubs and knives.

Xinhua says the police first fired warning shots.

The reports have not been independently confirmed.

The shooting happened in the provincial capital, Urumqi, a little more than a week after bloody clashes broke out there between Uighurs and members of China's ethnic Han majority.

The violence left 184 people dead and 1,680 people wounded.

China's Uighurs complain of religious and cultural persecution, and say an influx of Han in the area is taking away their economic opportunities.

The Uighurs' Muslim religion and Turkic language link them more to their Central Asian neighbors than to China's ethnic Han majority.
