An improvised explosive device (IED) exploded in the municipality of Sultan Sumagka (Talitay), Maguindanao Saturday, sometime after a gathering for peace and unity was held in the municipal gymnasium.

Nobody was reported killed or hurt in the attack.

Sultan Sumagka police chief Razul Pandulo said that while the IED has yet to be forensically examined, they determined that it was packed with nails as shrapnel and was equipped with a timer. The IED was left in Barangay Kiladap and exploded around 12 noon.

The IED was reportedly seen by motorists at the side of the National Highway going to Talitay proper.

Authorities have yet to determine the motive and the suspects behind the bombing.

Earlier, a thanksgiving “kanduli” or gathering for peace and unity was held in the municipality’s gymnasium, which was attended by hundreds of residents.
