In China, thousands of government forces have swept into a restive city in the Xinjiang region amidst the country’s worst ethnic violence in decades. Tensions have flared in the city of Urumqi between China’s ethnic Han Chinese and the ethnic Uyghurs, a Muslim minority. Some 156 people have been killed, more than 1,000 wounded, and more than 1,400 arrested so far. Both sides blame the other for the violence. Chinese President Hu Jintao has cut short a visit to Italy for the G8 summit, which opens in Italy today.
