There were conflicting accounts about how the fighting started. A spokesman for Juma Khan Hamdard, who is from Mazar-i-Sharif but is the governor of the southern Paktia province, said the convoy was headed south when it was attacked by gunmen wearing police uniforms.
The spokesman Ruhollah Samoon, who was in the convoy when the gunbattle broke out, said Hamdard had been visiting his family and was en route back to Paktia province with a stop planned in Kabul.
Police spokesman Shir Jan Duran, however, said the bodyguards clashed with police at a checkpoint outside Mazar-i-Sharif, and he said four policemen were wounded. He said authorities were investigating the shooting.
Munir Ahmad, a spokesman for the local government in Balkh province, said Hamdard's convoy didn't stop at the checkpoint, prompting the gunbattle. The reports couldn't be independently confirmed.
The violence came as Afghanistan is facing a major political crisis amid allegations of massive fraud in a June 14 runoff vote between Abdullah Abdullah and Ashraf Ghani Ahmadzai, who are vying to replace Karzai, who is constitutionally barred from seeking a third term.
In other violence today, a mortar shell slammed into a home in the eastern province of Nangarhar, killing one child and wounding five others, provincial government spokesman Ahmad Zia Abdulzai said.
Abdulzai said the attack took place in the Momand Dara district and all the children were from the same family. Nobody claimed responsibility for the attack, which occurred in a very remote area, but Abdulzai said the Taliban often fire rockets and mortar shells toward villages.
