The FBI reportedly warned California police departments in February that Iran could retaliate against the U.S., if it were to conduct strikes, by using drones aimed at the West Coast, according to an alert viewed by ABC News.

The alert, distributed at the end of February, told law enforcement that the FBI had “recently acquired information that as of early February 2026, Iran allegedly aspired to conduct a surprise attack using unmanned aerial vehicles from an unidentified vessel off the coast of the United States Homeland, specifically against unspecified targets in California, in the event that the U.S. conducted strikes against Iran.”
