Police Lieutenant General Archayon Kraithong, spokesman for the Royal Thai Police Office, said the suspects were being grilled to find out whether it was an isolated attack or connected to a terror network.

Prime Minister Paetongtarn Shinawatra, who was in Hua Hin, offered her condolences to the families of the victims.

Ms Shinawatra, the daughter of former PM and ex-Man City owner Thaksin Shinawatra, said she has ordered the Royal Thai Police and security agencies to investigate the attack, track down the perpetrators and take care of the injured and families of those killed.

The PM also instructed the police to increase security at all festive event venues during the holiday season.
