Officials in Afghanistan say Taleban militants have beheaded four Afghan men.

Authorities say the decapitated bodies were found in Shajoy district of insurgent-hit Zabol province. They say the men were kidnapped from their homes Tuesday.

The Taleban claimed responsibility, accusing the men of spying for the United States.

That claim could not be immediately confirmed.

Also Friday, a roadside bomb exploded as a convoy carrying Denmark's defense chief, Jesper Helsoe, passed by. The explosion occurred near Feyzabad in the northeastern part of the country. No casualties were reported.

Late Thursday, coalition leaders announced the deaths of 14 militants during the ongoing military offensive to flush out insurgents from southern Afghanistan.

The Taleban, whose government was toppled by a U.S.-led military coalition in late 2001, have been fighting against the new government.
