Bangkok mall bomb

In Bangkok, Thailand, small homemade explosives were detonated on the walkway between the Paragon shopping mall and a train line on Feb. 1, injuring one person. Police said that the pipe bombs were not constructed to be deadly.

No one has taken responsibility for the bombing, but police have evidence that the bombs are of the same type that accidentally exploded, killing two men who were transporting them, in March 2014. Authorities suspect those bombs were meant to target government locations.
