A bomb has exploded close to a shrine in the centre of the Thai capital, Bangkok, police say.
Local reports suggest at least 12 people have died and dozens have been injured.
The BBC's Jonathan Head, who is at the scene, says there is a huge amount of chaos, with body parts scattered everywhere.
The attack took place close to the Erawan Shrine in the capital's central Chidlom district.
Our correspondent says this a very well known shrine in the centre of Bangkok, next to a five-star hotel.
He says people around the shrine were hit by the full force of the blast.
