A suicide bomber in a car blew himself up next to a NATO convoy in southern Afghanistan on Friday, but no troops were hurt.
The blast occurred north of Tirin Kot, the capital of Uruzgan province.
Afghan police say the suicide bomber was trying to get close to the convoy but was more than 30 meters away when the explosion went off.
The bomber was killed, but there were no other casualties.
Attacks from suspected Taleban militants against NATO, U.S. and Afghan forces increased dramatically in Afghanistan last year. U.S. and Afghan officials have warned they expect an increase in Taleban attacks in the coming months. Some information for this report was provided by AP.
