Pakistani Taleban have beheaded two government officials in the northwestern Swat Valley in revenge for the killing of two insurgent commanders by security forces, a militant spokesman said on Sunday. Their bodies were dumped beside a road. The two government officials were kidnapped and beheaded on Saturday evening in Khuwaza Kheil, a village 18 km north of the valley's main town of Mingora, said town police chief Danishwar Khan. “They beheaded the officers. We've sent an ambulance to pick up the bodies,” Khan said. Militant spokesman Muslim Khan said the beheadings were revenge for the killing of two low-level Taleban commanders earlier on Saturday. Authorities struck a peace deal in February aimed at ending militant violence in the former tourist valley of Swat but the militants have refused to disarm and pushed out of the valley into neighboring districts. Islamic court set up in NWFP: P8 The Pakistani Taleban aggression raised alarm in the US and in Islamabad, and a week ago the security forces launched an offensive to expel militants from two of Swat's neighboring districts. More than 170 militants have since been killed. The army launched the offensive to clear militants from the Dir and Buner districts after US Secretary of State Hillary Clinton accused the government of abdicating to the Taleban. In another attack, Taleban militants shot dead an Afghan national in Pakistan's semi-autonomous North Waziristan tribal region after accusing him of spying for the United States, a police official said Sunday. The bullet-ridden body of Fazal Haq, 28, was found on Sunday dumped by the side of a road in Naurak village, east of Miranshah. “Haq, who was kidnapped two months ago, had multiple bullet wounds on his body,” local tribal police official Omar Niaz said.
