(AP) — Two attackers have blown themselves up outside a packed Roman Catholic cathedral during a Palm Sunday Mass on Indonesia’s Sulawesi island, wounding at least 20 people. A video obtained by The Associated Press showed body parts scattered near a burning motorbike at the gates of the Sacred Heart of Jesus Cathedral in Makassar, the capital of South Sulawesi province. A priest at the church said he had just finished celebrating Mass when the explosion went off. He said security guards at the church were suspicious of two people on a motorcycle who wanted to enter the building and when they went to confront them, one of them detonated explosives. The wounded included four guards and several churchgoers.
