The toll includes at least 21 firefighters — making the disaster the deadliest for Chinese firefighters in more than six decades. Several remain missing.

A total of 720 people were injured in the disaster in Tianjin, a key port and petrochemical hub east of Beijing.

Chinese authorities have ordered the evacuation of a 3-kilometer (1.8-mile) zone around the northern port city of Tianjin over chemical contamination fears from blasts and fires that continue to rage.

Police and military staff are deployed at checkpoints leading to the explosion site, and helicopters are hovering above.

Burning flames are still visible on Saturday, and explosions have been reported by witnesses and state media.

Authorities are yet to determine the full list of chemicals on site. State media say there are large amounts of sodium cyanides, which is combustible upon contact with water.
