U-S cracks down on electronics on flights from Mideast and North Africa

The U-S Homeland Security department isn't explaining why most carry-on electronics are being barred on certain North American-bound flights from the Mideast and North Africa.
    
But starting today, laptops, iPads, cameras and other gear larger than a cellphone will have to be placed in checked luggage.
    
Officials say the ban will affect nine airlines that were to be informed at 3 a-m Eastern Time.
    
The affected non-stop flights originate from 10 airports in eight countries.
    
The ban was first revealed Monday by Royal Jordanian Airlines, which said its flights to New York, Chicago, Detroit and Montreal will be affected.
