Five people were killed after a three-story house caught fire and later collapsed in Bangkok on Saturday, according to local authorities.

A firefighter, three rescue workers and a resident were killed and six others were seriously injured, according to Bangkok Governor Aswin Kwanmuang, who scrambled to the scene alongside city officials.

The bodies of the deceased were dragged out by fellow rescue workers from the debris.

The other seven residents of the house managed to get out to safety, the governor said.

Police will investigate the cause of the blaze at the house, which had been turned into a home office in Thawi Watthana district of Bangkok.
