The deputy governor of Afghanistan's southern Kandahar province has been killed in a suicide attack, officials have said.
Abdul Latif Ashna's convoy was attacked as he was being driven to work in Kandahar city.
His spokesman said a suicide bomber on a motorcycle slammed into his car. Three of his bodyguards were wounded in the attack, the spokesman added.
A Taliban spokesman claimed responsibility for the attack.
Thousands of US-led forces are fighting insurgents in the province.
US condemnation"Deputy governor Abdul Latif Ashna had just left his home and was on his way to his office when a suicide bomber on a motorcycle blew himself up near his vehicle," Kandahar governor Tooryalai Wesa said.
A Taliban spokesman later said it carried out the attack.
"One of our jihadists... blew up his motorcycle near the vehicle of Abdul Latif Ashna, the deputy governor of Kandahar, killing the deputy governor," Taliban spokesman Yousuf Ahmadi was quoted as saying by the AFP news agency.
The BBC's Quentin Sommerville, in Kabul, says that this type of targeted assassination is a tactic that has been used on a number of occasions by the Taliban.
US ambassador Karl Eikenberry, who was visiting Kandahar on Saturday, condemned the attack but said it would not blunt attempts to defeat the insurgency.
