An injured man rests at dining hall of a primary school, which has been turned into a shelter for people living nearby, near the site of the explosions at the Binhai new district, Tianjin, August 13, 2015. Officials from the northeast Chinese city of Tianjin, where two huge blasts in warehouses containing toxic chemicals and gas killed 44 people, said just a week ago they had discussed tightening safety standards with companies at the port.
