A suicide bomber blew himself up near a NATO base in eastern Afghanistan Tuesday, killing 10 civilians and wounding 14 others.

An Afghan official, provincial governor Arsala Jamal, says the bomber set off his explosives in a crowd of laborers waiting to get inside a NATO military base in the city of Khost.

There were no NATO or U.S. casualities.

In a separate incident in the south, suspected Taleban militants ambushed a police patrol in Kandahar, killing at least eight policemen.

Attacks by 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 in what has been called a "spring offensive."
