In late February, the FBI distributed an alert to police departments in California stating it had acquired information that, as of early February 2026, Iran allegedly aspired to conduct a surprise attack using unmanned aerial vehicles launched from an unidentified vessel off the coast of the U.S. homeland, targeting unspecified locations in California if the United States conducted strikes against Iran. The alert stated the FBI had no additional information on timing, method, target, or perpetrators.
The warning coincided with the Trump administrationâs ongoing military assault against Iran, while Iran has retaliated with drone strikes in the Middle East. An FBI spokeswoman in Los Angeles declined to comment, and the White House did not immediately respond to a request for comment.
California Gov. Gavin Newsomâs office said the Governorâs Office of Emergency Services is working with state, local, and federal security officials. The Los Angeles County Sheriffâs Department reported an elevated readiness posture, including increased patrols around places of worship, cultural institutions, and other prominent locations, and reviewed deployment plans and resource availability.
