A suicide bomber blew himself up at an entrance to Afghanistan's Bagram Airfield on Monday, an attack the Taliban called revenge for the burning of Qurans by U.S. troops there last month.
The blast at the base, north of Kabul, killed two civilians and wounded two others, Interior Ministry spokesman Sediq Seddiqi said.
A Taliban spokesman claimed 12 U.S. soldiers, including Special Forces members, and nine Afghans were killed in the blast, part of the group's "revenge campaign" for the Quran burning.
