The attack took place just a few hours ago in the city of Kandahar. The director of culture and youth of Kandahar was among the at least nine people who were injured in the attack.
Reports from the scene say the bomber rammed his car into the white SUV carrying the governor, Asadullah Khalid.
The attack comes just days after the Taliban had requested they be able to bury the body of one of their top commanders, Mullah Dadullah, who was killed over the weekend. Gov. Khalid instead put the body on display for journalists outside his office.
"I can confirm that Mullah Dadullah has been killed, and his dead body is outside my office, and everyone, journalists and ordinary people, can come and see his dead body," Khalid told reporters over the weekend.
Later, the governor had the body buried in Kandahar but said if Dadullah's family made contact with him, they could rebury him elsewhere.
