The police shot and killed 11 rioters at the scene and captured another four who were injured.

The US said it is closely following the reports of violence, as well as urged China to conduct a thorough and transparent investigation and to provide due process and legal protection to those have been detained.

The US State Department spokesman Patrick Ventrell said the US remained "deeply concerned" by the ongoing reports of discrimination and restrictions against Uygurs and Muslims in China.

"We have taken note of the remarks made by the US State Department spokesman," Hua said, adding that China is unsatisfied with the spokesman's remarks, as well as US criticism of China's ethnic and religious policies

Hua said the US has been a victim of terrorism and is fully aware of the danger posed by terrorism.

China hopes the US will work with the international community to fight terrorism and enhance international anti-terrorism cooperation, she said.
