A person familiar with the situation said the Biden administration was behind the curve as things deteriorated in Afghanistan. "Every decision has come too late and in reaction to events that make the subsequent decision obsolete," the source said.
Local embassy employees who have been at home for weeks were left to make their own way to the airport, the source said, adding that emails were sent to them on Sunday after sporadic gunfire to remain in their houses or some other safe location.
The pandemonium hampering the evacuations prompted some embassy officials to raise concerns that there was an insufficient number of U.S. troops to secure the airport, reflecting poor planning and intelligence failures, said the source.
The source and another U.S. official told Reuters that the administration so badly misjudged the situation that the State Department flew a regular rotation of diplomats into Kabul last Tuesday even as the Taliban advanced toward the capital.
