KABUL, Afghanistan - A suicide bomber struck at the heart of NATO's operation in Kabul on Saturday, killing at least six Afghan civilians in an attack that officials blamed on the Haqqani network - which the United States has designated a terrorist organization.
The blast, which left a bloody stain on a sidewalk just outside the headquarters of the U.S.-led military coalition, came as a senior Haqqani commander interviewed by the Associated Press vowed revenge for Washington's decision.
The Obama administration gave the Pakistan-based Haqqani network, which is linked to the Taliban, a terrorist label Friday despite misgivings the move could further stall planned Afghan peace talks.
