Chinese authorities ordered a mass evacuation on Saturday of everyone within 3 kilometers of the site of a massive explosion late Wednesday in the port city of Tianjin, according to multiple media reports. Some media outlets, including CNN, reported that there were additional explosions at the site on Saturday.
The evacuation was due to fears of the potential spread of chemical contamination, the reports said. The evacuees included those housed at shelters for those left homeless by the blasts, the reports said.

The death toll from the initial Wednesday blasts was reported at 85 on Saturday, including 21 firefighters, with more than 700 reported injured.
Investigators are continuing to search for clues as to precisely what caused the explosions at the warehouse, which is designed to house toxic chemicals and gas. Citing police reports, Reuters said that the warehouse mainly stored ammonium nitrate, potassium nitrate and calcium carbide at the time of the blasts.
Chemical experts suspect that an explosion could have been caused if firefighters, who had been called to attend a fire in the area shortly before the blast, sprayed the calcium carbide with water. Calcium carbide reacts with water to create acetylene, a highly explosive gas, they said.
