U.S. law enforcement agencies in California have received a security alert from the Federal Bureau of Investigation warning about the possibility that Iran could attempt a retaliatory attack on American soil amid the ongoing conflict between the United States and Iran.

The alert, which was distributed to police departments and security officials, outlines intelligence suggesting that Iranian operatives may have considered launching a “surprise attack” using unmanned aerial vehicles (UAVs) from a vessel located off the U.S. West Coast.

While authorities say the information does not indicate a confirmed or imminent attack, the warning reflects heightened concern among federal and state officials as tensions between the two countries continue to escalate.

Intelligence Warning Sent to California Authorities

According to the FBI alert cited by multiple reports, intelligence obtained earlier in 2026 suggested that Iran had explored the possibility of launching drone attacks from an unidentified vessel positioned near the U.S. coastline.

The potential targets were described as “unspecified locations in California.”

The document reportedly stated:

“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 U.S. conducted strikes against Iran.”

However, the alert also emphasized that investigators do not currently have additional details about timing, targets, or individuals involved.

Officials stressed that such intelligence notices are part of routine information-sharing intended to help local agencies remain vigilant during periods of increased international tension.

Heightened Readiness in California

Following the alert, law enforcement agencies across California have taken precautionary steps to increase preparedness.

The Los Angeles County Sheriff’s Department confirmed that it is maintaining an elevated level of readiness in response to global developments.

In a public statement, the department said it had increased patrols around several sensitive locations, including:

Places of worship

Cultural institutions

Community centers

Other prominent public locations

Officials explained that these measures are being taken out of an abundance of caution, not because of a specific confirmed threat.

The department also said it has reviewed emergency response plans and ensured that additional resources can be deployed quickly if necessary.

Coordination With State and Federal Agencies

California officials say they are working closely with federal authorities to monitor the situation.

A spokesperson for California Governor Gavin Newsom’s office stated that the state’s emergency management teams are coordinating with security agencies at multiple levels.

“The Governor’s Office of Emergency Services is actively working with state, local, and federal security officials to protect our communities,” the statement said.

Such coordination typically involves sharing intelligence updates, evaluating potential risks, and preparing response strategies should any credible threat emerge.

Conflict Between the U.S. and Iran Continues

The security alert comes amid ongoing military tensions between the United States and Iran.

Over the past two weeks, U.S. and allied forces have conducted strikes against Iranian targets, part of a broader confrontation that has raised concerns about a wider regional conflict.

Iran has responded with drone and missile attacks aimed at U.S. and allied assets across the Middle East.

In addition to these military exchanges, the situation has intensified around the Strait of Hormuz, one of the most important shipping routes for global oil supplies.

Recent reports from major news organizations indicated that Iranian forces may have begun deploying naval mines in the strait, a move that could disrupt international shipping.

Approximately 20 percent of the world’s oil supply passes through this narrow waterway, making it a critical artery for global energy markets.

U.S. Response to Mine Deployment

President Donald Trump responded strongly to reports of Iranian mining operations in the region.

The president warned that any attempt to block shipping traffic in the Strait of Hormuz would trigger severe military consequences.

He stated that vessels attempting to deploy mines would be “dealt with quickly and violently.”

Shortly afterward, the Pentagon confirmed that U.S. forces had destroyed multiple vessels believed to be involved in mine-laying operations.

According to military officials, 16 mine-laying ships were sunk near the strait, significantly reducing Iran’s ability to interfere with shipping traffic.

Trump also commented on the operation through social media, stating that several boats used for mine deployment had been destroyed and that additional actions could follow.

Escalating Threats and Retaliation

Throughout the conflict, leaders in both countries have issued strong warnings.

Iranian officials have threatened retaliation against U.S. forces and interests, while American officials have vowed to respond forcefully to any attacks.

U.S. Secretary of War Pete Hegseth recently stated that American intelligence agencies had disrupted an alleged plot targeting President Trump.

According to Hegseth, U.S. forces eliminated a group believed to be planning an assassination attempt against the president.

Although details surrounding that claim remain limited, the report underscores the high level of tension currently surrounding the conflict.

Concerns About Possible Attacks on U.S. Soil

Security experts say that when conflicts escalate overseas, authorities often increase monitoring for potential retaliatory actions at home.

These actions can take several forms, including cyberattacks, disinformation campaigns, or attempts to target infrastructure or symbolic locations.

The FBI alert regarding a potential drone attack from an offshore vessel represents one possible scenario that intelligence agencies are considering.

Drone technology has become increasingly common in modern conflicts, allowing attacks to be launched remotely with relatively small aircraft.

In recent years, both military and non-state actors have used drones for surveillance and offensive operations.

Because drones can be launched from various locations—including ships at sea—security officials are paying close attention to maritime activity near U.S. coastlines.

No Confirmed Attack Plans

Despite the seriousness of the warning, authorities stress that the intelligence report does not confirm that an attack is planned or imminent.

Instead, it reflects a possible scenario that analysts believe Iran may have considered under certain circumstances.

Such warnings are frequently shared with local law enforcement so agencies can remain alert and prepared if additional intelligence emerges.

Experts note that proactive information-sharing is a key part of modern security strategies.

By distributing alerts early, federal agencies allow local authorities to review response plans and ensure they are ready to act if necessary.

Public Safety and Awareness

For residents in California and across the United States, officials emphasize that there is no immediate cause for alarm.

Law enforcement agencies continue to monitor the situation while maintaining routine security operations.

At the same time, authorities encourage the public to remain aware of their surroundings and report suspicious activity to local law enforcement.

Community awareness can play an important role in preventing or responding to potential security threats.

A Period of Global Uncertainty

The FBI’s warning highlights the broader climate of uncertainty surrounding the conflict between the United States and Iran.

As military operations and political tensions continue to evolve, governments and security agencies around the world are closely watching developments.

For now, law enforcement officials in California and across the country remain focused on preparedness, coordination, and protecting communities.

While the intelligence warning reflects the seriousness of the current geopolitical situation, authorities emphasize that vigilance and cooperation between agencies are key to maintaining public safety during periods of heightened international tension.
