The United States has said that as many as 1,500 Americans may be awaiting evacuation from Afghanistan amid growing warnings of terrorist threats targeting the Kabul airport.

Untold thousands of at-risk Afghans are struggling to get into the airport even as many thousands of other Afghans already had been flown to safety in nearly two weeks of round-the-clock flights.
