Sr. Insp. Willy Casuyo, spokesperson of the Cotabato City PNP, said they are still clueless as to the motive behind the bombing.
Casuyo theorized that the bomb exploded when it was still in the hands of one of the victims.
“Because of the impact of the explosion, the bodies of two persons were cut into parts and the vehicle that carried them was also torn into pieces,” he said.
The police said they have not received any warning or bomb threat the past days.
This was the second bomb in Cotabato City this year. On January 10, two persons were killed when an improvised explosive device blasted off along Almonte St., in Cotabato City.
Bombs also exploded in Kidapawan City and in General Santos that left six persons dead and at least 20 others injured.
