Acting on fears that terrorists can build bombs into laptops, Homeland Security has decided to expand the ban it imposed on Middle Eastern flights. Computers will now be checked as baggage.

The Department of Homeland Security plans to ban laptops in the cabins of all flights from Europe to the United States, European security officials told The Daily Beast. The announcement is expected Thursday.

Initially a ban on laptops and tablets was applied only to U.S.-bound flights from 10 airports in North Africa and the Middle East. The ban was based on U.S. fears that terrorists have found a way to convert laptops into bombs capable of bringing down an airplane. It is unclear if the European ban will also apply to tablets.

DHS said in a statement to The Daily Beast: “No final decisions have been made on expanding the restriction on large electronic devices in aircraft cabins; however, it is under consideration. DHS continues to evaluate the threat environment and will make changes when necessary to keep air travelers safe.”

However, this move is increasing fears in the aviation industry that as well as guarding against bombs this ban could actually endanger flights. Laptops and tablets denied access to the cabin and added to checked baggage means that devices with a history of lithium-ion battery fires could set off a deadly conflagration in a cargo hold — where no one can put out the fires.

The FAA recorded 33 incidents in 2016 of personal electronic devices carried into cabins by passengers causing fire emergencies during flights, according to an FAA document reviewed by The Daily Beast. Of these, three were in laptops and two in tablets.

Two of the most serious were on Delta flights and both involved laptops.
