“There were three explosions, but no dead,” Police Major General Wichai Sungprapai told AFP.
The circumstances of the explosions, which occurred in eastern Bangkok outside the main business and tourist areas, were unclear.
A man, believed to be Middle Eastern, had his legs torn off in one of the blasts on the side of a busy road, said Police Colonel Sithiparp Baiparaset.
He was admitted to Bangkok’s Chulalongkorn Hospital where he was receiving emergency treatment, an official at the hospital said.
The other blasts were reported to have occurred in a nearby house and road.
