Four people, including three boys, died while four others were wounded when a reported rifle grenade exploded in Sitio Raniag, Barangay Sinamar, this town, on Sunday morning, police said.
Among the fatalities were an 8-year-old Grade 3 pupil and his 85-year-old grandmother. Witnesses said they heard a loud explosion and later found the victims sprawled on the ground.
Police eventually determined the type of explosive device involved. The children had reportedly been playing with a metallic object believed to be an improvised explosive device shortly before the blast.
