Americans who requested to be evacuated from Afghanistan received a note from the State Department informing them that the U.S. can’t “guarantee” their security on the way to the Kabul airport, CBS News reported on Tuesday.

The State Department has a list of roughly 5,000 Americans who have requested to leave Afghanistan and roughly half of them received the note, according to CBS.

“Thank you for registering your request to be evacuated from Afghanistan….Please make your way to Hamid Karzai International Airport at this time,” the note reads. “PLEASE BE ADVISED THAT THE UNITED STATES CANNOT GUARANTEE YOUR SECURITY AS YOU MAKE THIS TRIP.”
