China explosion: Did warehouse operators violate safety rules?

Authorities increased the official death toll from a massive blast site at China's Tianjin port to 112 on Sunday, as teams rushed to clear dangerous chemicals and prosecutors prepared an investigation into those responsible for the disaster.

More than 700 people were injured and 95 people, including dozens of firefighters, are missing after a fire and rapid succession of blasts late Wednesday hit a warehouse for hazardous chemicals in a mostly industrial area of Tianjin, 120 kilometers (75 miles) east of Beijing.
