Recue workers try to work out a plan after a chemical storehouse blast near a highway toll station in Guangzhou, south China's Guangdong Province yesterday evening. As many as 8000 local residents were evacuated, including 4000 students. About 50 of the evacuees got poisoned by the gas released from burning chemicals, and were rushed to a local hospital. Most of them have been discharged, and no one death was reported. [China Foto Press]
