Ahmad Wali Karzai, a brother of Afghan President Hamid Karzai and one of the most powerful men in southern Afghanistan, was shot dead in his own home on Tuesday, the Interior Ministry said, according to Reuters. "Ahmad Wali Karzai was martyred by a bullet strike inside his house in Kandahar," the statement said. The head of the ministry's counter-terrorism unit earlier said Ahmad Wali was apparently killed by his own bodyguard.
