Some 1,500 Americans still in Afghanistan in last days of U.S. evacuation.

About 1,500 American citizens remain in Afghanistan, and about a third of them are in contact with the U.S. government and hope to leave in the coming days, Secretary of State Antony J. Blinken said on Wednesday.

Some of the remaining 1,000 may not want to leave, Mr. Blinken said, describing an ever-changing estimate that the Biden administration has grappled to pin down as American troops wind down an evacuation effort that has overwhelmed the airport in Kabul, the capital.
