Over a dozen people have been killed in two bomb blasts at a Roman Catholic cathedral on the southern Philippine island of Jolo, where the Abu Sayyaf group and other armed fighters are active.
Sunday’s incident claimed the lives of at least 15 civilians and five soldiers, police said, adding that 77 others were injured.
The number of fatalities was revised after police said earlier that 27 people were killed.
The first bomb went off in or near the cathedral of Jolo, the capital of Sulu province, followed by a second blast outside the compound as government forces were responding to the attack, security officials said.
The initial explosion scattered the wooden pews inside the Cathedral of Our Lady of Mount Carmel and blasted window glass panels, and the second bomb hurled human remains and debris across a town square fronting the church, witnesses said.
President Rodrigo Duterte’s spokesman Salvador Panelo condemned the “act of terrorism” and vowed that government forces will pursue the perpetrators of the attack.
“The Armed Forces of the Philippines will rise to the challenge and crush these criminals,” he said.
In a separate statement, the Philippine Army said the explosions were likely caused by improvised explosive devices (IEDs).
“We condemn this dastardly attack on the civilians who were peacefully attending church services,” a statement from the military said.
Photos on social media showed debris and bodies lying on a busy street outside the Cathedral of Our Lady of Mount Carmel, which has been hit by bombs in the past.
Troops in armored carriers sealed off the main road leading to the church while vehicles were transporting the dead and wounded to the hospital.
Some casualties were evacuated by air to nearby Zamboanga city.
“I have directed our troops to heighten their alert level, secure all places of worships and public places at once, and initiate proactive security measures to thwart hostile plans,” said Defense Secretary Delfin Lorenzana in a statement.
Jolo has long been troubled by the presence of Abu Sayyaf, an armed group blacklisted by the United States and the Philippines as a “terrorist organization” because of years of bombings, kidnappings and beheadings.
No one immediately claimed responsibility for the attack, according to Al Jazeera’s Jamela Alindogan, reporting from Manila.
“But the timing is suspicious because, last week, there was a referendum and the island of Jolo voted to not be part of this new autonomous government that is being created,” she said.
The Bangsamoro, meaning Moro nation, is an expanded autonomous region, that is expected to replace the existing ARMM, which has been criticized as merely nominal, and failed to end the violent conflict that has left at least 120,000 people dead over the past five decades.
On Friday, it was announced that voters in Mindanao overwhelmingly voted for the creation of the Bangsamoro. However, voters in Jolo and the entire Sulu province voted against the new regional unit.
Rebels and the government in Manila hope a new, peaceful Bangsamoro will finally draw the investment needed to pull the region out of the brutal poverty that makes it a hotspot for violence.
Muslim rebels have long been battling for the independence or autonomy on Mindanao, which they regard as their ancestral homeland dating back to when Arab traders arrived there in the 13th century.
