Assailants abducted and beheaded an Afghan intelligence service employee and struck one of the agency's vehicles with a remote-controlled bomb in a separate attack, killing six employees and wounding three, officials said on Monday.
The latest violence follows a bomb attack Sunday that killed two intelligence service officers, a soldier and a driver in Mehtar Lam, the capital of eastern Laghman province.
On Monday in Laghman's Alingar district, an intelligence service vehicle driving from neighboring Nuristan province was hit by a remote-controlled bomb, said provincial police chief Abdul Karim. He said six of the agency's workers were killed, while three others were wounded.
In Ghazni province, southwest of Kabul, an intelligence service employee was invited into a home, then kidnapped and beheaded Sunday by the Taliban, said deputy governor Mohammad Kazim Allayar. He said the owner of the house is currently under investigation.
On Saturday, a suicide bomber blew himself up in the eastern city of Khost, killing six civilians and wounding 40 others, officials said.
NATO and Afghan troops, meanwhile, pressed ahead with their largest-ever offensive launched last month in southern Afghanistan to flush out Taliban militants from the northern tip of opium-producing Helmand province.
