Assailants abducted and beheaded an Afghan intelligence service employee and bombed one of the agency's vehicles.
In Ghazni province, southwest of Kabul, the employee was invited into a home, then kidnapped and beheaded Sunday by the Taliban, said the deputy governor.
In Laghman province's Alingar district, an intelligence service vehicle was hit by a remote-controlled bomb, a police official said, adding that six of the agency's workers were killed and three wounded.
An intelligence service vehicle was also bombed in the same province on Sunday, in an attack that killed two.
In southern Zabul province, a roadside bomb killed two policemen and wounded five others.
Intelligence officers in Kabul discovered a large car bomb Monday in an old taxi parked in a crowded civilian area where Nato and US convoys often drive past. Authorities found a tank of gasoline, three gallons of explosive chemicals, three grenades and a mortar in the car.
There have been at least three suicide bomb attacks in Kabul this year, but the areas worst plagued by violence are the southern and eastern provinces.
There have been 39 suicide attacks in the first three months of 2007, a threefold increase compared to the same period last year, according to the Afghanistan NGO Safety Office.
