The official Xinhua news agency said the fight erupted between a group of Han Chinese and ethnic Uighur workers from Xinjiang at a factory in Shaoguan, Guangdong province, after a rumour spread that some Uighurs had raped two women. Xinhua, citing police, said 13 people had been detained, including three from Xinjiang, for taking part in the fight. Two others were suspected of spreading rumours on the Internet. "Relevant departments have required police to strengthen their work on this serious criminal case in order to stabilise society," Xinhua quoted a government official as saying. Nearly all Uighurs to whom Reuters spoke in Xinjiang's regional capital Urumqi, where at least 156 people died in the weekend riots, traced the protests back to their own anger over the confrontation in southern China.
