NATO-led forces say a Taliban suicide truck bomber has attacked a coalition outpost in central Afghanistan, killing two Afghan civilians.

The coalition said Sunday that 77 NATO personnel and nearly 25 Afghan civilians received non-life-threatening injuries in the blast on the eve of the 10th anniversary of the September 11 terror attacks against the United States.

The Taliban has claimed responsibility for Saturday's attack.

The international alliance said the truck exploded at the entrance of the Combat Outpost Sayed Abad in Wardak province. It said the brunt of the explosion was absorbed by the protective barrier at the entrance.

The attack came hours after the Taliban lashed out at Washington, calling the 2001 U.S.-led invasion of Afghanistan that followed the September 11 terrorist attacks “a permanent stigma on the face of Western democracy.”

The Taliban accused the U.S. of using the terrorist attacks as a pretext to martyr innocent Muslims.
