The FBI warned police departments in California in recent days that Iran could retaliate for American attacks by launching drones at the West Coast, according to an alert reviewed by ABC News.

“We 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 State Homeland, specifically against unspecified targets in California, in the event that the US conducted strikes against Iran,” according to the alert distributed at the end of February. “We have no additional information on the timing, method, target, or perpetrators of this alleged attack.”

The warning came just as the Trump administration launched its ongoing assault against the Islamic Republic. Iran has been retaliating with drone strikes against targets throughout the Mideast.
