Bombings kill 27 at Philippines church

MANILA: The Philippines vowed to destroy those behind twin bombings that killed 27 people during a Sunday church service yesterday in the country’s restive south, six days after a referendum on autonomy for the mainly Muslim region returned an overwhelming ‘‘yes’’ vote.

The attack wounded 77 and was one of the deadliest in recent years in a region long plagued by instability. It came amid hope and excitement about the ratification of a devolution plan that aims to bring development, jobs and peace to one of Asia’s poorest and most volatile places.

The first explosion went off inside the cathedral on Jolo island, in Sulu province, and was followed by a second blast outside, that was detonated as security forces raced to the scene, officials said.

‘‘The enemies of the state have boldly challenged the capability of the government to secure the safety of the citizenry in that region,’’ said Salvador Panelo, spokesman of Philippine President Rodrigo Duterte.

‘‘The armed forces of the Philippines will rise to the challenge and crush these godless criminals.’’

There was no immediate claim of responsibility but police suspect the bombings were the work of the Abu Sayyaf, a militant group that has pledged allegiance to Islamic State and is notorious for its bombings and brutality.

‘‘They want to show force and sow chaos,’’ national police chief Oscar Albayalde said, suggesting the Abu Sayyaf group was the prime suspect. Jolo is a stronghold of the Abu Sayyaf, which runs a lucrative piracy and kidnapping operation that successive governments have failed to break up. The group, which operates in the waters and islands of western Mindanao, has beheaded numerous foreign captives when ransom payments were not met.

Pictures distributed by the military of the inside of the Jolo church showed several rows of wooden pews destroyed, with debris strewn across a blackened floor.
