Yancheng: Toxic yellow gas could be seen rising from the flames on Friday at the Tianjiayi Chemical plant in the city of Yancheng.

The death toll in the explosion at the plant in eastern China has risen to 47, with another 90 people seriously injured.

Firefighters and soldiers wore protective masks and suits to go into the chemical plant area, detecting air and water quality and searching and rescuing people trapped.
