China’s Tianjin industrial disaster marked one year on

It’s exactly one year since one of China’s worst industrial accidents. 173 people were killed after two huge explosions in the busy port of Tianjin. An official report blamed the blasts on hazardous chemicals stored illegally in a warehouse. To date, 25 people - including members of the government - remain under investigation.
