The half-brother of Afghan President Hamid Karzai was slain in his southern Afghanistan home by a bodyguard Tuesday.
A member of Ahmed Wali Karzai's security team reportedly shot him twice -- once in the head and once in the chest -- with an AK-47.
The Afghan president confirmed the murder, saying his brother's death reflects the overall suffering of the country.
Wali Karzai, who'd been the target of several prior murder attempts, was the focus of much criticism, including charges that he ran drugs and worked for the CIA.
"I cannot say whether this was political or personal or some other matter," said Noorolhaq Olomi, a former parliament member from Kandahar. "But whoever did it, it shows the weakness of this government."
"The president needs to change things," he added. "He needs to change himself and build a government that is real. Right now, there is no government. It's all a fraud."
According to The Associated Press, the Taliban has claimed responsibility for Tuesday's assassination.
