The half-brother of Afghan President Hamid Karzai was shot dead at his home in Kandahar on Tuesday, authorities said.
Ahmed Wali Karzai, the Kandahar provincial council chief, was killed during a gathering, said provincial governor Tooryalai Wesa. He did not know a motive.
While the governor initially said a friend killed Karzai, his spokesman later clarified that the death was at the hands of a guard.
The Taliban claimed responsibility for the shooting, saying that the guard accused of shooting him was working for them.
