At least three people were killed and dozens injured after an explosive device was thrown into a crowd at a music festival in Thailand.
Thai police announced on Saturday that they had detained two suspects.
Just before midnight on Friday, an explosive device was thrown into a crowd during an outdoor performance at an annual festival in Umphang city, Tak province, which borders Myanmar, the Umphang Rescue Team Association said.
Police said at least 48 people were injured, but no charges have yet been filed against the suspects as the investigation continues.
Defense Ministry spokesperson Thanathip Sawanthan said local police reports said there was a fight between rival groups of men before the explosion, but there was no broader security threat. Evidence showed the explosive device was a homemade bomb, he said.
Tak Province concentrates its military presence in border areas including Umpang.
Prime Minister Pethuntarun Shinawatra expressed his condolences to the victims and their families.
Government spokesperson Jirayu Hoonsap said the prime minister had directed local security personnel and relevant agencies to investigate and rescue victims.
