A fire broke out on Monday at the site of two huge blasts in the Chinese port city of Tianjin more than two weeks ago, Tianjin Daily reported. The newspaper reported on its microblog that the fire erupted after rain came in contact with magnesium and sodium. It cited experts as saying it was a “normal chemical reaction” and there was no need to panic. Two huge blasts erupted at a warehouse storing dangerous chemicals on August 12. In all, 158 people were killed – 94 firefighters, 11 police officers and 53 civilians. The report came as more than 300 primary and middle schools in the Binhai New Area, where the warehouse is located, opened for the new school year on Monday as scheduled.
