A second explosion went off at Sathorn pier in Bangkok on Tuesday afternoon, following Monday's pipe bomb that killed at least 20 people and wounded more than 100.
The Bangkok Post reported that the bomb was thrown at about 1:20 p.m. local time from the bridge. It bounced into the water and exploded there.
Nobody has been reported injured. The Bangkok Post cited Transport Minister Prajin Juntong saying the bomb has been classified as an improvised explosive device (IED), and is similar to the one thrown yesterday at the Erawan shrine.
