Approximately 100 Americans are still trapped in Afghanistan, the White House said on Sunday, days after U.S. soldiers withdrew from the war-torn country.

The United States "is connected with all those whom we have consistently identified," staff chief Ron Klain said on the CNN "State of the Union" from the White House, although he was ambiguous about the intentions of removing US nationals from the Taliban country.

The White House expects Qataris to restart flight service from Kabul in the coming days, Klain added.

"If they do, we’re obviously going to look to see if Americans can be part of those flights," he said.

Reuters reported that Kabul's airport closed on Monday after US soldiers left, but regional flights resumed on Saturday.

According to Klain, the US is also in contact with Afghans who have been granted special immigration visas.

The State Department admitted last week that the "majority" of such visa holders — Afghans who worked for the US government — were still stranded in their native country.

They are said to include an Afghan interpreter who assisted in the rescue of President Joe Biden in 2008 when his helicopter was forced to land in a remote valley due to snowfall while he was touring the nation as a senator.

“We are going to try to get every person out,” Klain said when asked to comment on the report.
