A large crowd looking for flights out of Egypt waits at Cairo airport.

Far fewer Americans were evacuated from Egypt today than the the State Department had expected because widespread road closings kept many citizens from reaching the airport before the curfew, NBC News Courtney Kube reports.

After about 1,200 U.S citizens and their family members were evacuated Monday, just under 400 were flown to safe havens in Istanbul and Athens today. 

More than 3,000 U.S. citizens have now asked for help getting out of Egypt, and the State Department says it believes more haven't contacted the U.S. Embassy and are heading directly to the airport. 

The State Department says it will continue evacuations until every U.S. citizen who wants to leave is out.
