Airline passengers traveling from eight Middle Eastern nations, including Jordan and Egypt, will be barred from carrying large electronic devices into the main cabin under new regulations from the Trump administration.

The new rules, which come into effect on Tuesday, also apply to Saudi Arabia and the United Arab Emirates, according to a US official. Passengers from the eight countries will have to check laptop computers and other large devices, such as tablets, into the hold on all flights bound for airports in the US. But the restrictions will not apply to flights leaving the US for the same countries, according to the official, who requested anonymity.

The move marks the latest attempt by the Trump administration to tighten security after Mr Trump vowed during the presidential race to do more to tackle terrorism. It comes one week after his administration issued a revised travel ban that temporarily bars citizens of seven largely Muslim countries from entering the US. The revised order, like the first one, has been blocked by the courts, preventing implementation for the time being.

Royal Jordanian Airlines earlier on Monday warned its passengers about the new Department of Homeland Security regulations regarding large electronic devises. But the airline later removed a notice from its social media accounts, following suggestions that it had prematurely released information. While some outlets have reported that the ban applied to 13 countries, the US official said only eight nations were on the actual list.
