MANILA - Davao City Mayor Sara Duterte-Carpio on Wednesday said she is open to the possibility of extending martial law in Mindanao if the Armed Forces of the Philippines deems it necessary.

Duterte-Carpio made the statement after Executive Secretary Salvador Medialdea said extending martial law may be an option in the wake of the bombing in Sultan Kudarat that left at least 2 people dead and over 30 injured.

"Kung sa tan-aw sa atong (If in the view of our) Armed Forces of the Philippines, Office of the President, there is a need to extend the declaration of martial law in Mindanao, then we all follow the direction of the national government, particularly the Office of the President," the daughter of President Rodrigo Duterte said.

The blast in Isulan, Sultan Kudarat happened on Tuesday at around 9:15 in the evening, while the town was celebrating its 7th Hamungaya Festival. Among those who died were Lenie Ombrog, 52, and Davy Shane Alayon, 7.

Brig. Gen. Cirilito Sobejana, commander of the Army's 6th Infantry Division, said the improvised bomb exploded while several soldiers were chasing the still-unidentified culprit. They have yet to determine the motive behind the blast.

Duterte initially declared martial law in May 2017 when the Islamic State-inspired terrorists laid siege upon the southern city of Marawi. Congress extended martial law until the end of 2017 upon the President's request.

The Marawi siege ended in October 2017 but Duterte requested to extended martial law further for the rest of 2018, citing a lingering terror threat in Mindanao as well as the armed insurgency of the New People’s Army as his reason. Congress granted his request.

Several lawmakers questioned the Congress' decisions before the Supreme Court but both martial law extensions were upheld by the high court.
