DHAKA: The US is banning electronic devices from cabin baggage on flights from eight mainly Middle Eastern and North African countries.
A US government source told the BBC that the measure would affect nine airlines operating out of 10 airports.
US media reported the order was sparked by intelligence gathered overseas.
It will reportedly include all large electronic devices such as laptops, tablets cameras, DVD players and electronic games, but not phones.
The Department of Homeland Security (DHS) declined to comment on the issue but is expected to make an announcement on Tuesday.
Last February an aircraft operated by the Dubai-based carrier Daallo was damaged by an explosion shortly after take-off from the Somali capital, Mogadishu.
Investigators said a passenger who was sucked out of the plane had been carrying a laptop bomb.
The Islamic militant group al-Shabab, which is linked to al-Qaeda, claimed that it was responsible and the possibility of further such attacks is apparently what is now concerning American spies.
A formal list of the airlines affected has yet to be released, but an official speaking to the Associated Press (AP) said it would apply to the following 10 airports in eight countries:
Queen Alia International, Amman, Jordan
Cairo International Airport, Egypt
Ataturk Airport, Istanbul, Turkey
King Abdulaziz International, Jeddah, Saudi Arabia
King Khalid International, Riyadh, Saudi Arabia
Kuwait International Airport
Mohammed V International, Casablanca, Morocco
Hamad International, Doha, Qatar
Dubai International, United Arab Emirates
Abu Dhabi International, United Arab Emirates
