China's Hu leaves G8 summit over Xinjiang violence: report

Chinese President Hu Jintao has left the G8 summit in Italy to return to Beijing amid an outbreak of violence in the northwestern Xinjiang province, China's state-run Xinhua news agencyreported early Wednesday.

The move comes asofficials in Xinjiangimposed a curfewovernightas part of a crackdown on protesters after Han Chinese clashed with Uighurs in the provincial capital on Tuesday.

After bringing in riot police to break up multiple protests, the Xinjiang regional government announced that a curfew was tobe imposed from 9 p.m. Tuesday to 8 a.m.Wednesday local time.

The curfew is needed to "avoid further chaos," said Xinjiang Communist Party secretary Wang Lequan.

Riot police using loudspeakersappealed to about 300 marchers to stop their destructive behaviour as they threw rocks, smashed shop windows and knocked down food stalls run by ethnic Uighurs in Urumqi on Tuesday.

Many of the protesters waved wooden sticks, pipes and shovels while chanting "Unite" and "Modern society," according to eyewitness accounts.

"They attacked us. Now it's our turn to attack them," a man in the crowd told Reuters.

As the demonstrators entered a predominantly Muslim area andapproached a mosque, police used tear gas to break up the crowd.

The Han march followed an earlier protest by about 200 people from the Uighur minority thatresulted in a standoff with security forces and blocked a main road.

At least 156have died in ethnic violence in the northwestern province of Xinjiang since Sunday.

Uighur ex-pats protest

UN High Commissioner for Human Rights Navi Pillay said an extraordinarily high number of people had been killed and injured in the rioting, and shecalled for a full inquiry.

"I urge Uighur and Han civic leaders, and the Chinese authorities at all levels, to exercise great restraint so as not to spark further violence and loss of life," she said. "This is a major tragedy."

The European Union on Tuesday called for "restraint on all sides," adding it "deplores the loss of life and expresses its sympathy with the families of the victims."

Uighur expatriates also protested outside the Chinese embassies in Turkey and Norway on Tuesday.

Protesters briefly scuffled with police in Ankara, and the Turkish Foreign Ministry summoned a top Chinese diplomat over the violence in China.

In Oslo, at least two people were injured when roughly 100 Uighurs gathered outside the Chinese embassy. One received injuries while trying to scale the embassy fence.

Protesters waved the Uighur national flag and shouted slogans such as "Stop killing our brothers stop killing our sisters."

Exiled leader blames China

The Uighurs an ethnically Turkic, predominantly Muslim group make up the majority in Xinjiang, a region in northwest China bordering Central Asia and Mongolia.

Their relations have often been tense with the ethnic Han Chinese who predominate in the country. Many Uighurs feel they're discriminated against by the government in Beijing and a Uighur separatist movement has existed for decades.

The protests started in the provincial capital of Urumqi on Sunday, when demonstrators gathered to demand justice for two Uighurs killed in June during a fight with their Han co-workers at a factory in southern China.

The protests turned into the deadliest ethnic unrest in the region in decades.

Speaking at a rally in Washington on Tuesday, exiled Uighur leader Rebiya Kadeerblamed the Chinese government for the violence. About 100 people chanted "Shame on China" as they marched to the Chinese Embassy.

Chinese officials have blamed Kadeer, who headsthe Uighur American Association (UAA), for inciting violence. Kadeer, who has lived in Fairfax, Va., since she was exiled from China four years ago, denies the charges.
