International passengers planning to fly to the U.S. are being warned to bring charged electronics because if security cannot turn on the device they will be turned away at security checkpoints.
The Department of Homeland Security issued an order Sunday for “certain airports overseas.”
“During the security examination, officers may also ask that owners power up some devices, including cell phones,” Homeland Security said in a statement. “Powerless devices will not be permitted onboard the aircraft. The traveler may also undergo additional screening.”
The statement did not specify which airports or countries will be affected.
The news comes two weeks after the U.S. reported a credible threat from terror groups developing non-metallic, non-detectable bombs to evade airport security.
The Transportation Security Administration has no jurisdiction over foreign airports, but the U.S. requires certain measures be taken in order for an airline to fly non-stop service to American cities.
