Beijing says ethnic Muslim Uighurs targeted Han Chinese
Chinese police have arrested 1,434 people over rioting in Xinjiang province, official state media say.
Rioting broke out on Sunday in Urumqi - the capital of Xinjiang - leaving 156 people dead and more than 800 injured.
Unrest has continued, with hundreds of Uighurs facing off against police in Urumqi on Tuesday, and protests around a mosque in Kashgar on Monday.
Beijing blames ethnic Muslim Uighurs for the violence, but exiled Uighurs say police fired on students.
Demonstrators said they had been demanding justice for two Uighurs killed last month in a fight with ethnic Han Chinese at a factory in southern China.
The bloodshed drew international concern, with the US calling for all sides to "exercise restraint".
The official Chinese news agency Xinhua reported on Monday that police believed agitators were "trying to organise more unrest" in other cities in Xinjiang, a mountainous and desert region that borders Central Asia.
About 200 people "trying to gather" at the Id Kah mosque in the centre of Kashgar, on the ancient Silk Road, were dispersed by police early on Monday evening, Xinhua said.
Police also revealed they had information about efforts to organise unrest in the city of Aksu and the Yili prefecture, Xinhua added. Yili is a border region that was hit by ethnic unrest in the late 1990s.
Calm in Urumqi
As relative calm returned to the bloodstained streets of Urumqi, paramilitary police patrolled the main bazaar - a largely Uighur neighbourhood - carrying batons, bamboo poles and slingshots.
Extremist forces inside and outside of China communicated with each other intensively before the incident erupted
