Two foreign nationals, one of them Swiss, have been stoned to death in the Afghan capital, a government official said on Sunday. Bodies of the men were discovered in Baghe Chilstone, an ancient garden not far from the city's center, Interior Ministry spokesman Lufullah Mashal, told Reuters. "Locals informed the police and showed them the bodies and an investigation is going on as to who stoned these to death, and why," Mashal said. "One of them holds a Swiss passport and the nationality of the other is not known." Both had come from neighboring Pakistan nine days ago, said Khalil Aminzada, deputy chief of Kabul police. He said the two were wearing local shalwar (baggy trousers) and long shirts as well as woolen hats. The two were pelted last night with bricks and stones and their bodies were being examined by local forensic experts, he added. **PHOTO CAPTION*** Former Guantanamo Bay detainee Osman, 50 (L) embraces a relative in Kabul, following his release along with 22 other Afghans.
