One of the most powerful men in Afghanistan was assassinated this morning when Ahmed Wali Karzai, half-brother of President Hamid Karzai and provincial council chairman of Kandahar, was shot dead in his home by a police commander who was a close family associate. The assassin, Sardar Mohammed was killed by Karzai's security detail. The Taliban claimed responsibility for the death almost immediately, though those claims could not be verified. Daoud Sultanzoy, a member of the Afghan parliament, speaks about Karzai's death from Kabul. Joshua Foust, a fellow at the American Security Project and author of "Afghanistan Journal: Selections from Registan.net," talks about what's next for NATO's fight against the Taliban in southern Afghanistan.
