Rescuers work at the accident site of a chemical plant blast in Zhangzhou, southeast China's Fujian Province, April 7, 2015. A xylene facility leaked oil and caught fire, which led to blasts and a fire at three nearby oil storage tanks at Tenglong Aromatic Hydrocarbon (Zhangzhou) Co. Ltd. on the Gulei Peninsula in Zhangzhou City at 6:56 p.m. (1056GMT) on Monday. The blaze was put out 21 hours after the blast here which injured six, said local authorities on Tuesday.
