An Afghan provincial governor for southern Logar province was killed when his vehicle was blown up by a roadside bomb on Saturday, police said.
Abdullah Wardak and three of his bodyguards were killed in Paghman district of Kabul province on their way to Logar, some 40 kilometres south of Kabul city, said Abdul Razaaq, police chief of the district, reported dpa.
"It was around 8:00 am (0330 GMT) that a roadside bomb was remotely detonated when the governor's vehicle was passing by," Razaaq said.
Barna Karimi, deputy director for the local governance department, an entity that oversees the work of provincial governor, also confirmed the death of the governor.
No group immediately took responsibility for the attack.
Taliban militants, who lost power in late 2001, use suicide and roadside attack as part of their campaign to toppled the western-backed Afghan government.
