SANTIAGO, Chile (AP) — The fiery explosion of a homemade bomb killed a man in downtown Santiago on Thursday, officials said, adding to a string of blasts in Chile’s capital.

Prosecutor Claudio Orellana initially said the man was handling the bomb when it exploded about 1 a.m., but he later opened the possibility that the man was a bystander. Witnesses posted online photos of the man in flames before he was taken to an emergency clinic where he died.
