An Ethnic Uygur man watches as an army truck full of Chinese soldiers patrols the street in Urumqi in China's far west Xinjiang province on July 8, 2009. China poured troops into the restive city of Urumqi in a massive show of force, but fresh unrest flared as Han Chinese and Muslim Uighurs armed themselves with makeshift weapons. As one of the worst spikes in ethnic tensions to have hit China in decades showed no signs of easing, President Hu Jintao abandoned a Group of Eight summit in Italy to deal with the crisis.
