Chinese state media has reported more than 800 people have been injured as a result of riots and streets battles.
And the death toll is climbing in what some have called the deadliest unrest in China since the Tiananmen Square crackdown 20 years ago.
A new round of armed military officers have hit the street in the remote area of northwest China, known as Xingjiang province.
Observers said tensions between Uighurs and the majority Han Chinese are never far from the surface in this area.
Uighurs are the region's ethnic Muslim population, who said in the face of tough econimic times they are being marginalized in their homelands, as more Chinese migrants pour in.
Some hit the streets to protest but they take a violent turn.
Police poured into the streets to stop rioters, but the streets burned even hours after the protests turned violent.
The Chinese government has said Uighurs have ties to Al Qaeda.
But Amnesty International said Chinese leaders are using the war on terror to justify its harsh repression of people who have lived in this region for years.
And in some places, internet access to video and images of these protests have been blocked.
But Uighurs are not giving up their fight to maintain dominance in the region -- a region where the violence has killed more than 150 people -- and injured more than 800.
