MIRANSHAH (Agencies) Taliban militants have beheaded four tribesmen accused of spying for US forces, police said. The bodies of four men were found near Mir Ali town in North Waziristan tribal district, which borders Afghanistan. Officials said the four were kidnapped by the Taliban about ten days ago. Gul Akber Khan, who lives in the village of Srakhula, just outside of Mir Ali, said he heard gunshots in the middle of the night. When he went to the mosque for morning prayers a few hours later, he found the bodies dumped along the road into Miramnshah, the main city in the tribal region. Notes found with the bodies said the men were killed for spying for the US, police official Nisar Khan told AFP. Mr Khan said the dead men had themselves killed several Taliban and ordinary people. A local security official confirmed the incident. Militants frequently kidnap and kill local tribesmen for spying for the Pakistani Government or US forces, who are battling a Taliban-led insurgency in Afghanistan.
