A former US Marine badly injured in Afghanistan has described the withdrawal in 2021 as a “catastrophe” in testimony before Congress.
Tyler Vargas-Andrews spoke in the first of a series of Republican-led hearings examining the Biden administration’s handling of the withdrawal.
He detailed a period of chaos and unpreparedness in the days after the Taliban captured Kabul.
Others spoke of enduring trauma and moral injury in the aftermath.
Sgt Vargas-Andrews, 25, was one of several US military personnel tasked with protecting Kabul’s airport on 26 August 2021, when two suicide bombers attacked crowds of Afghans trying to flee the Taliban during the US evacuation.
Thirteen US soldiers died in the bombing, along with 170 Afghan civilians.
Sgt Vargas-Andrews testified that he and another marine had received intelligence about the bombing before it occurred, and that he had spotted the suspect in the crowd.
He said he had alerted his supervisors and requested permission to act but had never received it.
“Plain and simple, we were ignored,” Sgt Vargas-Andrews said.
In emotional testimony, he described being thrown in the air during the bombing and opening his eyes to see his comrades dead or lying unconscious around him.
“My body was overwhelmed from the trauma of the blast. My abdomen had been ripped open. Every inch of my exposed body took ball bearings and shrapnel,” he said.
Sgt Vargas-Andrews called the withdrawal a “catastrophe,” adding: “There was an inexcusable lack of accountability and negligence.”
“I see the faces of all of those we could not save, those we left behind,” he said.
The House Foreign Affairs Committee inquiry into the evacuation from Afghanistan also heard from other US soldiers and veterans who spoke of the mental health toll that the withdrawal has had on them.
Retired Lt Col David Scott Mann, who worked to evacuate Afghans at the time, testified that the experience working to get allies out had been “gutting”.
He added that calls to the Veteran Affairs hotline spiked 81% after the withdrawal from Afghanistan, and he warned that the US was on the “front end of a mental health tsunami”.
He said a friend he had served with had died by suicide in the aftermath.
“He just couldn’t find his way out of the darkness of that moral injury,” Lt Col Mann said.
Testimony from the majority of witnesses placed the blame on every presidential administration since US troops were first deployed to Afghanistan, from George W Bush to Joe Biden.
Witnesses also urged for immediate action to help Afghan allies who had worked with US soldiers who are now in limbo both in Afghanistan and in the US.
“America is building a nasty reputation for multi-generational systemic abandonment of our allies where we leave a smouldering human refuse, from the Montagnards of Vietnam to the Kurds in Syria,” Lt Col Mann said.
Republicans who had long pushed for an investigation placed the blame on the Biden administration.
Panel chairman Mike McCaul, a House Republican from Texas, said the withdrawal had been a “systemic breakdown of the federal government at every level, and a stunning failure of leadership by the Biden administration”.
In response, Democrats spoke out in defence of President Biden.
House representative Gregory Meeks from New York said that Mr Biden had “made the right decision to bring all our troops home”.
“I can’t in good conscience imagine sending more American men and women to fight in Afghanistan.”
Mr Biden had previously said that he bore “responsibility for fundamentally all that has happened” but he also blamed former President Donald Trump for overseeing the withdrawal deal with the Taliban.
