Firefight between gov't forces, armed group reported in Maguindanao del Sur

Continuous gunfire was heard outside the compound of the Shariff Saydona Mustapha municipal government compound in Maguindanao del Sur on Monday.

GMA News' Jun Veneracion reported from the municipal compound and said a Special Action Force (SAF) armored vehicle had already entered the area as gunfire continued outside.

Some of the shots could be heard hitting metal structures and trees within the compound.

Authorities have yet to confirm which armed group was responsible for the shooting.

Residents estimated that the gunfire had been ongoing for more than two hours.

Despite the incident, the situation did not appear to affect voting at a nearby polling center for the first parliamentary polls in Bangsamoro Autonomous Region in Muslim Mindanao (BARMM).—Joviland Rita/AOL, GMA News
