Rahim Khan's bullet-ridden body was found late Friday near the village of Alikhel, 12 kilometers (around eight miles) west of Miranshah, the main town in North Waziristan.

"A note left on the body said Rahim was spying for the US forces stationed across the border and has met his fate," a security official in Miranshah, where Pakistani forces are battling Taliban and Al-Qaeda fighters sheltering in the region, told AFP.

Militants linked to Afgha-nistan's ousted Taliban militia have killed several pro-government tribesmen and Afghan refugees in the lawless region in recent months on charges of spying for US forces.
