Passengers traveling from 10 airports in eight Middle East and African countries will be barred from bringing laptops and other large electronics into the cabin as carry-ons starting as early as Tuesday.Two Middle Eastern-based airlines tweeted on Monday that passengers would not be allowed to bring laptops, Kindles, iPads and other electronics on flights heading to the U.S.

Unnamed officials told CNN that the move was to address a security concern involving passengers boarding non-stop flights to the United States from airports in specific countries. The officials did not specify the countries but did say the ban would be in effect for a limited period of time.
U.S. airlines will not be affected since none fly non-stop to any of the countries singled out in the directive, according to the CNN report.
