NATO says a Taliban suicide truck bomber has attacked a coalition outpost in Afghanistan.

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

A NATO statement says there were a “significant number of injuries.” The statement said none of the injuries is immediately life threatening.

The Associated Press says two civilians were killed in the blast.

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.
