Violence in China's restive western region of Xinjiang has left 129 people dead, state media say - a sharp increase on an earlier reported toll.
Reports previously said only three people had died and more than 20 had been injured in the city of Urumqi.
Xinhua news agency said police restored order after demonstrators attacked passers-by and set fire to vehicles.
The government has blamed separatist Uighurs based abroad and exiles led by a US-based businesswoman.
They were accused of orchestrating attacks on majority ethnic Han Chinese.
Uighur exiles said police had fired indiscriminately on a peaceful protest.
An overnight curfew was imposed, as activists reported multiple arrests.
'Foreign plot'
Eyewitnesses said the violence started on Sunday with a few hundred people, and grew to more than 1,000.

Xinhua says the protesters carried knives, bricks and batons, smashed cars and stores, and fought with security forces.
Uighur groups insisted a peaceful protest had become victim to state violence.
The Xinjiang government has blamed the latest unrest on Rebiya Kadeer, the Uighurs' leader who is living in exile in the United States.
"An initial investigation showed the violence was masterminded by the separatist World Uighur Congress led by Rebiya Kadeer," the government said in a statement, according to Xinhua.
It said the violence had been "instigated and directed from abroad".
The BBC's Quentin Sommerville in China says Xinjiang, a mainly Muslim area, has been a source of tension for many years.
Some of its Uighur population of about eight million, want to break away from China, and its majority Han Chinese population.
The authorities say police are securing order across the region and anyone disrupting order will be detained and punished.
