Afghanistan Says It Will Not Free Prisoners

South Korea and relatives of 21 kidnapped Koreans appealed for U. S. help but Afghanistan said for the first time that it will not release insurgent prisoners - the Taliban's key demand to free the captives. Afghan police found the body of the second hostage slain since the Christian church group was seized nearly two weeks ago. The group's pastor was killed last week. A supposed Taliban spokesman, meanwhile, said some of the prisoners the militants want released are held at the U.S. base at Bagram.
