This was stated by Republican lawmakers, noting that the administration of President Joe Biden did not prioritize their evacuation, Reuters reports.
"This is particularly relevant given the reports that some former Afghan soldiers have fled to Iran," said a report by the US House Foreign Affairs Committee marking the first anniversary of the Taliban's capture of Kabul.
The Biden administration, the authors of the report note, during the chaotic operation to withdraw American troops from Kabul International Airport on August 14-30, 2021, failed to prioritize the evacuation of Afghan special forces and other elite units trained in the United States.
The US administration is calling the operation an "outstanding success" that has evacuated more than 124,000 Americans and Afghans and ended the "endless" war.
However, hundreds of US-trained former security personnel and their families remain in Afghanistan amid reports that the Taliban are killing and torturing former Afghan officials.
Those former employees "may be recruited or forced to work for one of America's adversaries that maintain a presence in Afghanistan, including Russia, China or Iran," the Republican report said.
This is a serious risk to US national security, as these Afghans "know the tactics, methods and procedures of the US military and the intelligence community," according to the report's authors.
The Taliban occupied Kabul on August 15, 2021 - just over 2 weeks before the deadline for the withdrawal of US troops from Afghanistan.
The Americans and their allies organized a large-scale evacuation from Afghanistan of Western diplomats and civilians, including Afghans who feared reprisals from the Taliban.
In total, more than 120,000 people were deported.
On August 30, the American army completed the withdrawal of its forces from the territory of Afghanistan.
American troops have been in Afghanistan for almost 20 years.
