A provincial spokesman says a roadside bomb has killed a district chief in eastern Afghanistan and three of his bodyguards. Laghman provincial government spokesman Sarhadi Zewak says the government's top official in Alishang district was driving to a meeting when his car was blown up in the road. Zewak says it was not clear if the bomb had been remotely detonated or if the vehicle - a Toyota Corolla - had struck some sort of trigger. Zewak says they believe district chief Faridullah Niazi was being directly targeted by insurgents, according to a report of the Associated Press.
