Attack on NATO convoy kills 17 in Afghanistan

The blast occurred on the same day that a man wearing an Afghan army uniform killed three Australian soldiers and an Afghan interpreter in the south - attacks that show the resiliency of the insurgency and are likely to raise new doubts about the unpopular 10-year-old war and the Western strategy of trying to talk peace with the Taliban.

A spokesman for the fundamentalist Islamic movement, which was ousted in the 2001 invasion for its affiliation with al-Qaida, claimed responsibility for the Kabul attack, saying the bomber had used 1,540 pounds (700 kilograms) of explosives.
