A U.S. military plane that ferried some U.S. citizens out of Cairo today had actually been sent in to Egypt to deliver additional security for the U.S. Embassy in Cairo, NBC News' Jim Miklaszewski and Courtney Kube report.

The plane brought in the 10 to 12 Marines to augment the security force already in Cairo. Rather than let it leave the country empty, the U.S. military agreed to fill the plane with U.S. citizens trying to leave the country. The flight took the Americans to Larnaca, Cyprus.
The State Department has also sent in additional agents of the Bureau of Diplomatic Security to help with security needs in Cairo.
