U.S. law enforcement agencies in California were recently warned that Iran may have explored the possibility of launching drone attacks against targets on the West Coast in retaliation for Operation Epic Fury, according to a federal alert reviewed by ABC News.
The bulletin, circulated by the FBI to police departments in late February, said authorities obtained information indicating that, as of early February 2026, Iran had allegedly aspired to conduct a surprise attack using kamikaze drones launched from an unidentified vessel off the U.S. coast. The potential targets were described only as unspecified locations in California.
"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 States homeland, specifically against unspecified targets in California, in the event that the US conducted strikes against Iran," the alert said, adding that investigators have "no additional information on the timing, method, target, or perpetrators of this alleged attack."
The warning was issued amid the ongoing US-Israeli military assault against Iran. Tehran has responded with drone strikes against targets across the Middle East, raising concerns among U.S. officials about possible retaliation beyond the region.
A spokesperson for the FBI's Los Angeles field office declined to comment on the alert. The White House did not immediately respond to requests for comment.
The question is what exactly was the information obtained in early February that prompted the FBI to release a bulletin by late in the month.
We should note that on Feb. 3, we highlighted a threat assessment published by the Russian military-focused Telegram channel Rybar, which warned that potential Russian drones in Cuba could put critical oil and gas infrastructure in the Gulf of America, as well as data centers and military installations across the homeland, within range of these cheap, low-cost kamikaze drones.
Around that same time, we also warned that the explosion in AI data center buildouts would require next-generation counter-drone security, including kinetic interceptors. The Gulf states quickly learned during Iran’s retaliatory strikes that data centers and other civilian infrastructure were very much in play.
Separately, U.S. intelligence officials have also been monitoring the growing use of drones by Mexican drug cartels and the potential for such technology to be used against U.S. personnel along the southern border. A September 2025 intelligence bulletin reviewed by ABC News said an uncorroborated report suggested unidentified cartel leaders had authorized attacks using drones carrying explosives against U.S. law enforcement and military personnel near the border.
The document noted that such an attack inside the United States would be unprecedented, though it described the scenario as plausible. It also cautioned that cartels generally avoid actions that could trigger significant retaliation from U.S. authorities.
John Cohen, an ABC News contributor and former acting undersecretary for intelligence at the Department of Homeland Security, said the possibility of drone-based threats emerging from both the Pacific and Mexico is a growing concern for security officials.
"We know Iran has an extensive presence in Mexico and South America, they have relationships, they have the drones and now they have the incentive to conduct attacks," Cohen said. "The FBI is smart for putting this warning out so that state and locals can be better able to prepare and respond to these types of threats. Information like this is critically important for law enforcement."
The FBI alert did not specify how a vessel carrying attack drones could approach the U.S. mainland without detection. However, intelligence officials have long worried that equipment could be pre-positioned either on land or aboard ships at sea for use in the event of military strikes by the U.S. or Israel against Iran.
