The attack came after a barrage of bombings in Kabul where foreign armed forces had just completed a security mission. The suicide bomber detonated a suicide vest, killing 21 people who local officials said were anti-Taliban militiamen, four of them commanders. The Taliban claimed responsibility for the attack as well as for the bombings in Kabul that killed at least 51 people on Friday.
