GHAZNI, Afghanistan, Aug 28 (Reuters) - Taliban insurgents have agreed to free 19 South Korean hostages they have been holding for nearly six weeks, a Taliban negotiator said on Tuesday. South Korean negotiators had agreed to a set of Taliban demands as part of a deal for the release of the hostages, said the Taliban representative, Qari Mohammad Bashir. But the Taliban demands did not include their main previous condition -- the release of a group of militants held prisoner by the Afghan government.
