There has been fresh ethnic turmoil on the streets of China’s far-west, with reports of more hypodermic needle attacks. Police drove off with an 11-year-old boy said to be a victim.One Han Chinese man in strife-torn Urumqi said three Uighurs stabbed the child with poisonous needles and ran away. “The attackers must be punished by law,” said another man, complaining that those behind the stabbings are being taken away by police for their own protection. Despite reports of some return to normality, strife-torn Urumqi was again under heavy security today. “They have arrested many people but also released a lot of them” said a Han Chinese woman. “Until now, they have not judged and punished them. The Uighurs are just bullying us, the Han Chinese people, and now we have this spate of needle attacks.” Also in charge during July’s ethnic riots in Urumqi that claimed nearly 200 lives, the city’s Communist Party chief was today dismissed by Beijing. It follows days of protests by Han Chinese over the security situation in Xinjiang region. Police have used tear gas to break up the crowds in demonstrations that have left at least five people dead.
