The U.S. government has rolled out new restrictions for fliers from certain Mid-east and African countries.

The U.S. government is prohibiting passengers from 10 airports in eight countries from carrying on most electronics on nonstop flights coming into the U.S., the Associated Press reports. The passengers will be allowed to carry on cell phones, but most other electronics, like iPads, laptops and cameras will have to go in their checked bags. The new rules may take effect Tuesday.

Government officials told the AP they were doing this based on “evaluated intelligence” about possible threats, but did not give information on timing of the threat or whether a particular terrorist group might be behind the potential threat.

The ban impacts flights from international airports in Amman, Jordan; Cairo; Kuwait City, Kuwait; Istanbul; Jeddah and Riyadh, Saudi Arabia; Casablanca, Morocco; Doha, Qatar; and Dubai and Abu Dhabi in the United Arab Emirates. This will impact roughly 50 flights per day, and officials told AP that the airlines have 96 hours to comply with this request or risk getting barred from landing in the United States.

Two airlines, Emirates and Etihad Airways, told Reuters Tuesday they had not been told about the new electronics rules.
