>> The Philippines has vowed to crush those behind a twin bombing attack at the cathedral on Sunday in which 20 people were killed. The attack took place on the Island of Jolo in the country's restive southern Sulu Province and comes just days after a referendum on greater autonomy on the majority Muslim region returned an overwhelming, yes vote.
> The island is a stronghold for the Abu Sayaff militant group, which has pledged allegiance to Islamic State. Police suspect they are behind the bombing. The first explosion went off inside the cathedral. A second detonated outside. Civilians bore the brunt, though five soldiers were also killed.
It comes amid excitement at the creation of an autonomous area called Bangsamoro backed by 85% of voters that aims to bring development and jobs to one of Asia's poorest and most volatile areas.
lu was one of the few areas that rejected autonomy, but will still be part of the new entity when it's fully formed in 2022.
The referendum came amid concerns about the presence of extremists in the Philippines including Abu Sayyaf, which is notorious for its lucrative piracy and kidnapping operations that successive governments have failed to break up.
