If this is true - and I understand that some would object to the source of the report - this sounds pretty consistent to how we reacted to a similar scenario of Americans under attack on 9/11/2012:

WND has learned from sources that the jihadists have closed down escape routes, and the U.S. Air Force is in a stand-down position. U.S. forces are not assisting even with air cover so a private extradition flight could land for a rescue, the sources said.
Privately scheduled exit flights have fallen through, sources said, as several private pilots originally scheduled to make the flights have quit.
The sources contend the U.S. military could provide the necessary air cover to protect C-130s or other air transport craft sufficient to make the evacuation, but so far officials have refused to get involved.
