Militants have killed three people accused of being spies for the US in North Waziristan Agency bordering Afghanistan, local officials said on Monday. The attackers slit their throats and left a note in the local Pashto language saying âanyone working as an American spy will meet the same fateâ, the official speaking on condition of anonymity said. Their bodies were found on Monday in a drain in the town of Tappi, 16 kilometers east of Miranshah, capital of the semi-autonomous region. Insurgents in the tribal areas, where Pakistani forces last year fought pitched battles with suspected Al Qaeda militants, have issued a hit-list of 28 local elders whom they called âgovernment spiesâ. In July, a Pakistani intelligence official was shot dead in nearby Mir Ali town, while another two tribesmen were killed in the same area in May for allegedly spying for the US.
