The United States has evacuated only about 3 percent of Afghans who worked for the American government and applied for special visas, leaving behind an estimated 78,000, according to a report released Tuesday.

The Afghans stuck in the Taliban-ruled country face increasingly desperate circumstances, the report by the nonprofit Association of Wartime Allies said.

“Their lives have been devastated by being left behind with seemingly no verifiable path to safety,” said the group, which helps Afghans who worked for the U.S. government during America’s 20-year-long war.
