The Pentagon is moving 3,000 Marines and soldiers to Afghanistan and another 4,000 troops to the region to evacuate most of the American Embassy and U.S. citizens in Kabul, as the Biden administration braces for a possible collapse of the Afghan government within the next month, administration and military officials said, according to The New York Times.

The sharply deteriorating situation in the country, as the Taliban rapidly advance across the north and Afghan security forces battle to defend ever shrinking territory in the south and west, has forced the Biden administration to accelerate plans to get Americans out.

President Biden, after meeting with his top national security advisers on Wednesday night and again Thursday morning, also ordered additional expedited flights out of the country for Afghans who have worked with the United States, so that their applications for special immigrant visas could be evaluated.

The embassy sent the latest in a series of alarming alerts, urging Americans to “leave Afghanistan immediately using available commercial flight options.”

And in Washington, the State Department spokesman, Ned Price, announced what he described as a drawdown of an unspecified number of civilians among the roughly 4,000 embassy personnel — including about 1,400 American citizens — to begin immediately.

“As we’ve said all along, the increased tempo of the Taliban military engagements and the resulting increase in violence and instability across Afghanistan is of grave concern,” he said. “We’ve been evaluating the security situation every day to determine how best to keep those serving at our embassy safe.”
