An explosion of a still unknown origin occurred at a pension house in Zamboanga City Sunday night, leaving at least three persons injured hours after two bombs were found in neighboring Isabela City, Basilan, police said.
Chief Supt. Elpidio de Asis, Zamboanga Peninsula regional police director, said the explosion happened around 9:25 p.m. at the Atilano Pension House in Brgy. Canelar.
It is not yet known if a bomb caused the blast, De Asis said, adding that members of the Zamboanga City Police are still in the area 10 p.m. to investigate.
Earlier in the day, two improvised explosive devices (IED) were found in Isabela City, which is just a 15-minute boat ride from Zamboanga City.
The first IED was found shortly before 2 p.m. near a store at the rotunda connecting Brgy. Aguada to Brgy. Mabarakat. Authorities found a triggering device, battery, and concrete nails after disrupting the bomb.
Around 2:50 p.m., another IED was found inside a plastic bag abandoned in Brgy. Aguada. It was disrupted arpund 3:45 p.m.
The bomb was composed of a blasting cap, two 9-volt batteries, a silicon control rectifier, two LED lights, a wireless doorbell, resistors, an improvised circuit board, a jack connector, slide switch, concrete nails, and a can containing what is believed to be ammonium nitrate with fuel oil, or ANFO.
It was still unknown if the explosion in Zamboanga City was connected to the planting of bombs in Isabela City.
Isabela City, though located in Basilan, is considered a part of the Zamboanga Peninsula after residents voted against its inclusion to the Autonomous Region in Muslim Mindanao during the November 1989 plebiscite. (John Roson)
