A bomb blast at a hospital in the Thai capital, Bangkok, wounded 24 people on Monday, the third anniversary of a 2014 military coup.
There was no claim of responsibility for the blast at the Phramongkutklao Hospital, which is popular with soldiers and their families and retired military officers.
“It was a bomb. We found the pieces that were used to make the bomb,” Kamthorn Aucharoen, commander of the police’s explosive ordnance team, told Reuters, adding it was not clear who was behind the attack.
“Right now, authorities are checking out closed circuit cameras,” Kamthorn said.
Government spokesman Sansern Kaewkamnerd said 24 people had been wounded. Most of the wounded were hit by flying glass, the military’s national security unit said.
Suspicion is likely to focus either on political dissidents opposed to military rule or Muslim separatists based in the south of the predominately Buddhist country.
Soldiers cordoned off the hospital’s entrance, a Reuters reporter at the scene said.
