The findings, released on Monday, refute assertions by some service members who believed they had a chance to take out the would-be bomber but did not get approval. And, for the first time, the USmilitary confirmed that the bomber was Abdul Rahman al-Logari, an Islamic State militant who had been in an Afghan prison but was released by the Taliban as the group took control of the country that summer.

The Abbey Gate bombing during the final chaotic days of the Afghanistan withdrawal killed 13 US service members and 170 Afghans, and wounded scores more. It triggered widespread debate and congressional criticism, fueled by emotional testimony from a Marine injured in the blast, who said snipers believed they saw the possible bomber but could not get approval to take him out.

Former Marine Sgt Tyler Vargas-Andrews told the House foreign affairs committee last March that Marines and others aiding in the evacuation were given descriptions of men believed to be plotting an attack. Vargas-Andrews, who was injured in the blast but not interviewed in the initial investigation, said he and others saw a man matching the description and might have been able to stop the attack, but requests to take action were denied.

In a detailed briefing to a small number of reporters, members of the team that carried out the review released photos of the bald man identified by military snipers as a potential threat and compared them with photos of al-Logari. The team members described facial recognition and other analysis they used confirmed those were not the same man.

“For the past two years, some service members have claimed that they had the bomber in their sights and they could have prevented the attack. We now know that is not correct,” said a team member.

They said they also showed the photo of the bald man to service members during the latest interviews, and that the troops again confirmed that was the suspicious man they had targeted.

The review notes that the bald man was first seen around 7am and that troops lost sight of him by 10am. The bombing was more than seven hours later, and the US says al-Logari did not get to Abbey Gate until “very shortly” before the blast took place.

Family members of those killed in the blast received similar briefings over the past two weekends and some are still unconvinced.

“For me, personally, we are still not clear. I believe Tyler saw what Tyler saw and he knows what he saw. And it was not the guy that they were claiming was the man in black,” Jim McCollum, the father of Marine Lance Cpl Rylee McCollum, told the Associated Press.

Critics have slammed the Biden administration for the catastrophic evacuation, and they have complained that no one was held accountable for it. And while the US was able to get more than 130,000 civilians out of the country during the panic after the Taliban took control of the government, there were horrifying images of desperate Afghans clinging to military aircraft as they lifted off.
