US-bound passengers travelling from about a dozen countries will be banned from carrying most electronic devices, officials have said.
Twelve carriers flying from about a dozen countries will be affected by the new rules, which could be announced later.
Some Middle Eastern airlines are affected, including airlines based in Jordan and Saudi Arabia, although the other countries were not named.
American carriers will not be affected.
Passengers will still be allowed to keep mobile phones and approved medical devices with them but anything larger, such as laptops, cameras and tablets, will only be permitted in checked luggage.
The ban has been under consideration since the US government learned of a terrorism threat several weeks ago.
Earlier on Monday, Royal Jordanian Airlines told its passengers that laptops, iPads, cameras and other electronics would not be allowed in carry-on luggage for US-bound flights from Tuesday.
