The Taliban claimed responsibility for the bombing, saying it was revenge for the burning of Qurans several weeks ago at the Bagram Air Base.

NATO officials said no coalition troops were harmed in the attack and that the bomber did not breach the base.

In eastern Afghanistan, authorities say a suicide bomber killed a member of the Afghan security forces and wounded 11 others in an attack on a police checkpoint in the city of Jalalabad.  No one immediately claimed responsibility for Monday's bombing.

When reports first surfaced February 20 of book burning at Bagram, violent anti-American protests erupted across Afghanistan, leaving at least 30 people dead and fraying relations between the U.S. and Afghanistan.
