NATIONWIDE - First it was the travel ban on Muslim countries, now travelers from several Middle Eastern countries are being singled out for a ban on flying with large electronics.

The U.S. government has temporarily barred iPads, cameras, laptops, and most other devices from carry-on luggage on non-stop flights that originate in 10 international airports.

Those airports are Cairo; Amman; Kuwait City; Casablanca; Doha, Riyadh, Jeddah; Istanbul; Abu Dhabi and Dubai.

Dubai-based Emirates says the ban is based on a security directive from the U.S. Transportation Security Administration and that it will take effect on Saturday.

Trump administration officials say the ban went into effect today but that airlines have 96 hours to implement it.

A U.S. official tells the Associated Press that the ban is indefinite, but the reason for it is unclear.

Some passengers at JFK Airport say they support the idea, while others say it's discriminatory.

"More scrutiny, more checks could help us prevent any further complications or security issues," said one traveler.

"Selecting eight particular countries, you know it's unfair, I mean it's Muslim countries, they're targeting Muslims again and it's just another Trump mistake," said another traveler.

Cellphones and medical devices are excluded from the ban.

But all other electronics on flights from those Middle Eastern countries must be packed in checked luggage.
