Kabul, Afghanistan - An explosion outside the home of Afghanistan's former vice president killed at least eight people Tuesday, government officials have said.
The explosion was near the Kabul residence of former vice-president Ahmad Zia Massoud, Afghan President Hamid Karzai told reporters. Massoud was not harmed in the attack.
Among those killed were one of Massoud's guards and an assistant, the former vice president's aide said. Forty others were wounded in the blast.
The explosion broke windows in a hotel a few blocks away.
Tuesday morning's explosion occurred as the Afghan president was at a nearby anti-corruption convention.
Karzai issued a statement condemning the attack, calling it inhumane and cowardly. The president called for a full scale investigation.
Massoud is a notable figure in Afghan politics. Not only was he a vice president of the county under Karzai, but his brother the late Ahmed Shah Massoud was heralded as a leader in the fight against the Taliban.
Ahmed Shah Massoud, the leader of the Northern Alliance, the Taliban's main opposition, was killed September 9, 2001, by a bomb inside a video camera during an interview at his headquarters with Tunisian al Qaeda operatives posing as journalists.
