At least 28 people have been left injured after two explosions shook an anti-government demonstration site in the Thai capital, Bangkok.
The Erawan medical centre, which tracks casualties, had initially put the toll at four, and said it could rise further.
The violence is the latest to hit the city as Thailand's increasingly volatile political crisis drags on.
It was not immediately clear what caused the blasts near Victory Monument, in the north of the city.
The protesters, who control several small patches of Bangkok, are vying to overthrow prime minister Yingluck Shinawatra's government and derail elections she called for February 2 in a bid to quell the crisis.
