The United States is arranging flights for later this month to evacuate Afghan interpreters and other staff who worked with U.S. forces, fearing they could be targeted by the Taliban, Bloomberg reports citing a senior administration official.

The relocation flights to neighboring countries will carry interested and eligible Afghan nationals and their families who are already in the application pipeline for the Special Immigrant Visa program, which allows those who have worked for U.S. and NATO forces to claim refugee status.

The Bloomberg reports notes that the Biden administration asked three Central Asian nations – Kazakhstan, Tajikistan and Uzbekistan – to temporarily house the Afghans as U.S. troops aim to complete their withdrawal from Afghanistan by the end of August, almost two decades after they first arrived to oust the Taliban government.

The White House said it would not disclose further details on when the flights will depart due to security reasons, but said they will begin in the last week of July.
