The US said that the decision was based on "evaluated intelligence", suggesting that the intelligence services have either intercepted a discussion about an extremist plot or been passed information by a source.
Aviation security experts were alarmed by an incident in Somalia last year when the insurgent group al-Shabaab smuggled an explosive-filled laptop on a flight out of Mogadishu, blowing a hole in the side of the plane. The aircraft was still low enough that the pilot was able to land the plane safely.
In a statement, the Department for Homeland Security said: "The US government is concerned about terrorists' ongoing interest in targeting commercial aviation, including transportation hubs over the past two years, as evidenced by the 2015 airliner downing in Egypt; the 2016 attempted airliner downing in Somalia; and the 2016 armed attacks against airports in Brussels and Istanbul.
"Evaluated intelligence indicates that terrorist groups continue to target commercial aviation, to include smuggling explosive devices in various consumer items."
US officials told CNN that the ban is related to a threat posed by Al-Qaeda."Evaluated intelligence indicates that terrorist groups continue to target commercial aviation and are aggressively pursuing innovative methods to undertake their attacks, to include smuggling explosive devices in various consumer items," an official said.
Airlines will be responsible for policing the cabin ban, and if they fail to do so could lose their rights to operate US routes. No end date has been put on the order, and officials would not say whether the restriction might spread to other airports.
The ban in the US hit Royal Jordanian, EgyptAir, Turkish Airlines, Saudi Airlines, Kuwait Airways, Royal Air Maroc, Qatar Airways, Emirates and Etihad Airways.
The airlines and their host governments have already been informed of the order by US officials, and some of them have begun informing passengers about the restriction.
Turkish Airlines put out a statement confirming the ban. "At Turkish Airlines we kindly inform our passengers that any electronic or electrical devices larger than a cell phone or smart phone (except medical devices) must not be transported on board in our flights arriving to the US destinations," it said.
