U.S. authorities believe drone technology could create new threats to the continental United States.

The devices could potentially be launched from vessels near the coast.

There is also concern about the possible use of drones near the southern border.

The warnings aim to ensure that state and local agencies prepare for emerging scenarios.

The FBI alert describes information recently obtained about an alleged Iranian plan.

According to the document, the plan may have been considered in early February 2026.

The supposed attack would involve drones launched from an unidentified vessel.

The potential targets would be unspecified locations in California.

The scenario would be triggered if the United States carried out attacks against Iran.

The alert was distributed in late February.

The document clarifies that no additional information is available.

Authorities do not know:

the timing of the attack

the exact method

specific targets

or the individuals responsible

The warning was issued as the administration of Donald Trump launched attacks against Iran.

Iran later responded with drone strikes on targets in several parts of the Middle East.

A spokesperson for the FBI’s Los Angeles office declined to comment on the alert.

The White House also did not immediately respond to requests for comment.

Concerns about drone use also include the U.S.-Mexico border

U.S. intelligence officials have also raised concerns about another threat.

That concern involves the growing use of drones by Mexican drug cartels.

Authorities fear that such technology could be used against U.S. personnel.

These concerns are focused particularly on the U.S.-Mexico border.

A bulletin from September 2025 reviewed by ABC News mentioned an uncorroborated report.

The report suggested that leaders of unidentified cartels may have authorized drone attacks carrying explosives.

The potential targets would be law enforcement officers and U.S. military personnel.

Such attacks would occur along the border.

This type of attack inside the United States would be unprecedented.

However, officials say the scenario is plausible.

Authorities note that cartels usually avoid actions that would trigger strong responses from U.S. law enforcement.

John Cohen, now an ABC News contributor, expressed concern.

Cohen mentioned the possibility of drone warfare originating from the Pacific Ocean and from Mexico.

He noted that Iran has a presence in Mexico and South America, maintains relationships in the region, and possesses drone capabilities.

According to Cohen, the country may now also have incentives to carry out attacks.

He said the FBI acted appropriately by issuing the warning about the Iran drone threat to California.

The information allows states and local governments to prepare and helps law enforcement agencies respond to potential threats.

U.S. intelligence officials have also warned for years about another risk.

That concern involves the pre-positioning of equipment, either on land or aboard ships.

Such preparations could allow attacks to be launched quickly if Israel or the United States were to strike Iran.

This scenario has long been discussed in national security circles.
