Casualties reported
There has been a large explosion close to a shrine in the centre of the Thai capital, Bangkok.
The BBC's Jonathan Head, who is at the scene, says there appear to be both dead and injured, amid a huge amount of chaos.
He says there is a massive amount of damage and a crater that indicates this could be a bomb.
Our correspondent says that if it is a bomb, this would be a rare attack for the capital.
