Suspected Islamic militants captured and beheaded a schoolteacher in Pakistan’s Afghan border area for allegedly spying for the US, an official said on Wednesday.The man’s body was found early on Tuesday in a large sack dumped by a road near Jandola, a town in the South Waziristan tribal district, said a local security official, who asked not to be identified.The area is a stronghold for pro-Taliban militants suspected of harboring al-Qaeda remnants in remote tribal regions along a porous, poorly-defined section of the border.Scores of people have been killed in the border zone in recent years due to suspicions that they collaborated with Pakistani authorities or spied for Washington. A note found with the beheaded man’s body identified him as “Akhtar Usman, the one who spied for America,” the official said. He said the forehead of the man’s head was inscribed with the word for “hypocrite” in Urdu, Pakistan’s main language.
