After inspecting the spot of the incident, police found an 81 mm mortar cartridge and a cellphone, which was possibly used to detonate the two homemade bombs, the inspector said.

Presidential spokesperson Ernesto Abella said that an investigation has been launched into the attack.

"As of the moment, initial but unofficial news feed state that there were no (intelligence) reports of bomb threats, nor has anybody claimed responsibility for the bombing," Abella told the local media.

No one has claimed responsibility for the attack yet and the investigators are trying to identify the perpetrators. The victims of the attack include around 10 children between the age of 7 and 15.
