AP - KABUL, Afghanistan – NATO forces say six Afghan police officers have been beheaded by insurgents in northern Afghanistan.

The military coalition said in a statement issued Wednesday the militants attacked a number of government buildings, including a police checkpoint, in Baghlan province's Dahanah-ye Ghori district. The insurgents overran the checkpoint Tuesday and killed the officers inside by cutting off their heads.

Local officials could not be immediately reached for comment.

Violence and casualties have surged in recent months in Afghanistan. June was the deadliest month for U.S. and international forces with the deaths of 103 service members, including 60 Americans.
