On January 27, the Cathedral of Our Lady of Mount Carmel was rocked with two blasts.
The Islamic State has claimed responsibility for the twin blasts at the cathedral, located in the southern island of Jolo.
Some 20 people - mostly church-goers - were reportedly dead with 100 more injured when the blasts had occurred.

According to Philippines authorities, the first blast happened inside the cathedral while the second happened at the compound when the authorities were conducting rescue efforts.
The bombs were made out of improvised explosive devices (IEDs). This marks the eighth time since the cathedral had been targeted by terrorists group since the first blast in June 2006.
Philippines President Rodrigo Duterte, who will be visiting the site of the blasts on January 28, has slammed the incident through his spokesperson Salvador Panelo.
"The Armed Forces of the Philippines will rise to the challenge and crush these godless criminals," Salvador was reported to have said.
Meanwhile, the United States of America joins Canada and the European Union in condemning the attack.
Even Pope Francis, leader of the world's 1.2 billion Catholics, has condemned the attack on the cathedral.
"I reiterate my strongest reprobation for this episode of violence which is once again plunging the Christian community into mourning," the Pope was reported to have had said during the World Youth Day celebrations in Panama.

Curiously, the twin blast happened following a referendum held almost a week back where Muslim majority regions in Southern Philippines voted to be ruled by Bangsamoro.
The region is to be led by the Moro Islamic Liberation Front (MILF) which will assume political power after laying down its guns following the polls.
The island of Jolo had voted not to be part of the 1.7 million who had been in favour of the the movement.
