Kabul, Nov 23, SPA -- Three U.N. workers kidnapped in Afghanistan have been released unharmed after more than three weeks in captivity, officials said Tuesday. "They are out," U.N. spokesman Manoel de Almeida e Silva said. Officials said the three were freed overnight and were in the Afghan capital. One Western official said doctors were examining the three at a NATO field hospital in Kabul. The hostages were released late Monday and are in good condition, three Afghan officials told The Associated Press on condition of anonymity. Armed men seized Philippine diplomat Angelito Nayan, British-Irish citizen Annetta Flanigan and Shqipe Hebibi of Kosovo in Kabul on Oct. 28, the first such abduction in the Afghan capital since the Taliban fell three years ago. Afghan officials earlier said they believed a criminal gang carried out the abductions, and that negotiations centered on a ransom demand.--SPA1136 Local Time 0836 GMT www.spa.gov.sa/218992
