Assassination in Afghanistan Creates a Void

A suicide bomber set off explosives concealed in his turban today in one of Kandahar's largest mosques. Hundreds of mourners were paying their respects to Ahmed Wali Karzai, President Hamid Karzai's half-brother, who was assassinated on Tuesday.  His death has created a power vacuum in the southern part of Afghanistan, destabilized the central government and threatened American efforts to cope with the Taliban and begin withdrawing troops before the end of the year.
