At least five dead, more than dozen injured in central Bangkok blast, local media say, citing Thai police.

Bangkok, Thailand (CNN)Police are sealing off the scene of a deadly blast near a popular Hindu shrine in central Bangkok because a bomb in the area remains active and needs to be defused, police at the scene told CNN on Monday.

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. The Bangkok Post reported several casualties.
