Just hours after Afghan Taliban militants said that they had killed a second South Korean hostage, Al Jazeera has aired a video showing several of the South Koreans being held. The station said the video was obtained outside Afghanistan. A Taliban spokesman said the kidnappers had shot dead a second hostage because the Afghan government was not listening to demands for the release of Taliban prisoners. The body of the first hostage killed, meanwhile, has been returned to South Korea. The Taliban seized the group of 23 Korean Christians eleven days ago.
