Two The incident occurred very early in the morning in Ruso district.
Two bodies, mangled from the blast, were found near the scene. They have been identified as Sorahudin Dolo, 30, and Abas Abu, of unknown age. Ninety M16 assault rifle cartridges and a mobile phone were found near the body of one of the dead men.
Local villagers saw three suspects on a motorcycle going to the scene, a roadside near the foot of a bridge, at around midnight. Two of them took the 5 kilogram bomb built into a metal box to bury it beside a roadside tree during heavy rain.
The bomb blew up due to an apparent short circuit. Sorahudin was killed, while the uninjured third man tried to help Abas, who had been seriously injured, taking him into the nearby rubber plantation.
Abas died from his wounds, so his friend then left the bodies and fled the scene.
Police believe that the bomb was intended to target a teacher protection unit which passes the area in the morning.
