Taliban militants shot dead an abducted Afghan in Pakistan's lawless northwest tribal region, accusing him of spying for the United States, an official said Monday. The bullet-riddled body of 30-year-old Islam-ud-din was found dumped by the road in the Sheratalla area, 40 kilometres (25 miles) north of Miranshah, the main town in the troubled North Waziristan region, near the Afghan border. "Islam, who was kidnapped two weeks ago, had multiple bullet wounds on his body," local police official Mehboob Khan said. A note found on the body said he was "spying for the US," the official said. Islamist militants weekly kidnap and kill tribesmen, accusing them of spying for the Pakistani government or for US forces, who are battling to quell a Taliban-led insurgency across the border in Afghanistan.
