New airplane electronics rules stem from ISIS-associated threat

The restrictions are on U.S.-bound flights from certain countries.

— -- New aviation security measures restricting electronic devices on flights from certain overseas airports were prompted by new threat intelligence obtained earlier this year indicating that ISIS associates were working on smuggling explosives-laden electronics onto U.S.-bound flights, ABC News has learned.

The U.S. government has deemed the threat information “substantiated” and “credible,” according to one source familiar with the intelligence.

Sources said that the airports – in eight Middle Eastern and African countries – affected by the restrictions were not directly named in the most recent threat intelligence gathered by authorities, but determined through intelligence analysis paired with other government information.

During an interview today, ABC News' Pierre Thomas asked a member of the House Intelligence Committee about the new DHS measures.
