According to officials, the bullet-ridden bodies of five men were found on Sunday dumped by the side of a road in Kamsarobi village, 30 kilometers (18 miles) south of Miranshah, the main town in the semi-autonomous North Waziristan tribal region.
"Taliban killed five men overnight, accusing them of spying for Americans to help them launch drone attacks," local police official Mehboob Shah told AFP. "A note found on the body said that the victims were spying on Taliban and anyone doing the same would be killed in this manner," he added.
The body of a sixth man was found in Qutabkhel village, five kilometers (three miles) south of Miranshah, with a similar note from the Taliban, Shah said, adding that he too appeared to have been shot dead overnight.
Another body of a man with a warning note from the Taliban was found near the town of Mir Ali, some 30-kilometres (18 miles) east of Miranshah, local police official Qayyum Khan told AFP.
An intelligence official and other local tribesmen confirmed the incidents.
Separately, a paramilitary soldier was killed and four others injured Sunday when Taliban militants fired a rocket at a convoy near Malik Deenkhel village in Khyber, another tribal district bordering Afghanistan.
