“The man who detonated a bomb outside the Kabul airport in August 2021, killing 170 Afghans and 13 American service members, was an Islamic State operative who had been held in a coalition detention facility in Afghanistan but was freed by the Taliban, according to a new U.S. military review that has identified him for the first time. Some service members who were at the airport that day claimed they had spotted the suicide bomber at the site and were ordered not to engage. But the review found that those service members had the wrong man in their sights, and the strike was not preventable. “There was no opportunity to engage the bomber prior to the attack,” said a senior U.S. military official, who was involved in the supplemental review. The bombing at Abbey Gate took place during the U.S. military’s chaotic exit from Afghanistan. Thousands of people had converged on the airport in a desperate effort to flee after the Taliban’s swift takeover of the country.”
