Nairobi: Five people were killed Monday when a minibus in northeast Kenya was destroyed by a roadside bomb during an ambush by armed men near the border of Somalia, police said. The attackers opened fire on the 14-seater vehicle after it ran over the explosive about eight kilometers (five miles) from Mandera town on the Kenya-Somali frontier. “A General Service Unit patrol team, which was on foot and close to the area, responded and engaged the attackers, who fled towards Somalia border direction,” a police report on the incident said. The attackers used guns and rocket-propelled grenades during the assault, the report added.
