A blast that appeared to target a Hindu shrine in central Bangkok on Monday killed several people and injured dozens more, according to Thai media reports citing local police.
Police were sealing off the scene because a bomb in the area remains active and needs to be defused, police at the scene told CNN.
Bomb squad members in blast suits responded to the area, and an officer announced over a loudspeaker, "The situation is still not safe. Please all stay back. There might be another bomb in the area."
Officials provided no immediate information on casualties and no bodies were visible, but there were five ambulances in the area. Some local media reported at least five people killed, while the Bangkok Post reported at least 15 deaths.
