Afghanistan - Masood Taliban authorities are denying involvement in a suicide bombing attack on the headquarters of an opposing guerilla group. It's believed that the leader of the battle against Taliban rule in Afghanistan may have been killed in the attack. But there are conflicting reports about Ahmed Shah Massood's condition after the explosion at his office on Sunday. Noah Adams talks with Ambassador Karl Inderfurth, who was Assistant Secretary of State for South Asian Affairs under President Clinton. He's now Visiting Professor of International Affairs at the George Washington University.
