Authorities say the bomber targeted a NATO convoy outside a U.S. base on a main road out of Kabul.

On Sunday, Taleban militants attacked a convoy in southern Afghanistan, killing up to 13 Afghan guards and wounding others who worked for a private security firm.

Officials said the convoy was attacked on the road from the capital, Kabul, to Kandahar.

Sunday's attack led to a long gun battle with insurgents that resulted in the death of five Taleban militants.

In another development, Britain's Defense Ministry said a British Royal Marine was killed during a military operation in southern Afghanistan on Sunday. The statement gave no other details.
