Following a series of U.S. military strikes on Iranian targets under the directive of President Donald Trump, the Federal Bureau of Investigation (FBI) has raised its counterterrorism alert across the nation. This precautionary measure anticipates potential retaliatory attacks by Iranian proxies.
On February 28, 2026, President Trump authorized significant military action, named Operation Epic Fury, in conjunction with Israel, targeting various Iranian positions. An FBI official confirmed that both counterterrorism and counterintelligence units are operating under increased vigilance. The duration of this heightened state of alert is currently unspecified, as the situation remains dynamic.
Historically, Iran has utilized a network of militant groups throughout the Middle East to execute attacks against Western interests. In response to the U.S.-led strikes, Iran launched retaliatory measures targeting American military bases in the region. Tehran has claimed responsibility for strikes on the U.S. Fifth Fleet service center in Bahrain, and reported attacks on facilities in Qatar, the United Arab Emirates, and Kuwait. These claims were accompanied by footage of an alleged Iranian drone collision with a Bahraini residential high-rise, the authenticity of which is under investigation.
Homeland Security Secretary Kristi Noem indicated her department's close collaboration with intelligence and law enforcement agencies to mitigate any threats to national security. "Homeland Security is in direct coordination with our federal intelligence and law enforcement partners as we continue to closely monitor and thwart any potential threats to the homeland," Noem stated.
The U.S. military employed Tomahawk missiles and dispatched Air Force and Navy aircraft in the assault on Iranian targets. While Iran's retaliatory attacks have occurred, the full extent of casualties and damages has not been confirmed. President Trump, acknowledging the inherent risks of military operations, expressed the potential human costs involved. "The lives of courageous American heroes may be lost, and we may have casualties," he said, as reported by the Daily Mail following the strikes.
Current efforts by U.S. officials are centered on preventing any overflow of conflict into domestic threats. Security experts have often highlighted the capabilities of Iranian-aligned groups like Hezbollah to conduct asymmetrical warfare outside conventional battlefields.
Major metropolitan law enforcement agencies are reviewing security protocols and observing for signs of emerging threats. While the Department of Homeland Security has not instituted specific new travel or infrastructure limitations, federal authorities are advocating for public vigilance without suggesting changes to daily routines.
As the situation unfolds, with continued hostilities between Iran and Israel and the presence of U.S. forces in the region, officials suggest that additional security measures may be implemented depending on how events progress.
