A chemical factory explosion has rocked the city outskirts of Bangkok, with the blast being heard kilometers away in the Samut Prakan province. The blast has damaged homes and thousands of evacuations have been ordered. 

It is currently unknown what caused the explosion at the expandable polystyrene producing factory. Firefighters have brought most of the inferno under control while a chemical styrene monomer tank still burns.

One rescue worker died, while 29 are injured.
