All primary and middle schools in Urumqi, capital of northwest China's Xinjiang Uygur Autonomous Region, resumed classes Monday after a 10-day closure. The schools had been closed since Sept. 4 because of traffic controls imposed in the wake of a spate of hypodermic syringe stabbings in the city and an A/H1N1 flu outbreak. Local authorities imposed the traffic controls as protestors took to the streets after hundreds of residents reported they had been stabbed by syringe needles. The temperatures of returning students will be taken before they enter their schools as the city is trying to contain flu outbreaks, said officials from the municipal education bureau Monday.
