President Marcos has strongly condemned the bombing, which killed four and hurt several others during a mass in Marawi City on Sunday morning, Dec. 3.

In a post on his X (formerly Twitter) account, the President said enemies of society carried out the act.

"I condemn in the strongest possible terms the senseless and most heinous acts perpetrated by foreign terrorists upon the Mindanao State University (MSU) and Marawi communities early this Sunday morning," he wrote.

"Extremists who wield violence against the innocent will always be regarded as enemies to our society," he added.

Marcos extended condolences to the victims of the bombing and vowed justice for them.

"I extend my most heartfelt condolences to the victims, their loved ones, and the communities that have been the target of this latest assault on peace," he said.

"Rest assured, we will bring the perpetrators of this ruthless act to justice," he added.

According to Marcos, the government is on top of the situation as he thanked the authorities for quickly responding to the victims' needs.

"We are in close coordination with the regional government of the Bangsamoro Autonomous Region in Muslim Mindanao (BARMM) and the concerned Local Government Units. I thank them for their swift and immediate response to the incident and for their ready support to the victims," he said.

"I have instructed the Philippine National Police (PNP) and the Armed Forces of the Philippines (AFP) to ensure the protection and safety of civilians and the security of affected and vulnerable communities. Additional security personnel are also being deployed," he added.

Meanwhile, President Marcos enjoined the public to remain calm and vigilant following the attack.

"As reports come in throughout the day, I enjoin all of us to remain calm, circumspect, and conscientious in our collective efforts to ensure that the horrific events of this morning are not further compounded by inaccurate, unvetted, and unofficial information," he said.

"Let us all keep the victims, their families, and our communities in our prayers," he added.

Based on initial reports, three women and one man died due to the explosion. Investigation into the incident is ongoing.
