His reason for choosing the event was particularly disturbing: He reportedly believed there would be “a lot of people.”
The case has drawn attention to Minnesota’s history of terrorist recruitment, the FBI’s use of undercover operations, and renewed questions about how authorities can identify radicalized individuals before they carry out violence.
Undercover FBI Operation Exposes Alleged Attack Plan
Investigators reportedly began examining Mohamud’s activities in December 2024, months before the alleged attack was scheduled to take place.
Over the following months, federal authorities gathered evidence suggesting that the teenager had developed an interest in joining overseas terrorist organizations before turning his attention toward an attack inside the United States.
According to the investigative account, Mohamud communicated with an FBI source about his extremist ambitions and eventually identified the Mall of America as his intended target.
He allegedly recorded a video declaring loyalty to ISIS and its leader, an act prosecutors could use as evidence of his ideological motivations.
The investigation reached a critical point when Mohamud sought to acquire a firearm capable of inflicting mass casualties.
Authorities say he requested an automatic weapon and subsequently arranged a transaction with someone he believed had connections to ISIS.
The supposed weapons supplier was actually working undercover for the FBI.
During the operation, Mohamud allegedly handed over $600 in exchange for an AK-47-style rifle, four magazines, and approximately 200 rounds of ammunition.
Agents moved in after he carried the weapon, concealed inside a duffel bag, toward his vehicle.
The arrest brought the alleged plot to an end before the planned October 24 attack.
The allegations remain subject to the judicial process, and Mohamud is presumed innocent unless proven guilty.
Minnesota’s Troubling History With Terrorist Recruitment
The allegations have revived scrutiny of a longstanding national security challenge in Minnesota.
For years, federal authorities have investigated recruitment efforts involving ISIS and al-Shabaab, the Somalia-based terrorist organization affiliated with al-Qaeda.
During the 2010s, Minneapolis became a significant focus of counterterrorism investigations after multiple young men from the region attempted to join extremist organizations overseas.
In 2015, federal prosecutors charged six Minnesota men in connection with an alleged conspiracy to travel to Syria and support ISIS.
That same year, al-Shabaab released propaganda encouraging attacks against Western shopping centers, explicitly identifying the Mall of America as a potential target.
The following year, a knife-wielding attacker injured ten people at a shopping mall in St. Cloud, Minnesota, before being fatally shot by an off-duty police officer. ISIS subsequently claimed responsibility, although the extent of its direct involvement remained unclear.
These incidents illustrate why Minnesota has remained an important focus for federal counterterrorism officials.
They do not, however, establish that Minnesota’s broader Somali-American community supports extremist violence. Recruitment investigations concern specific individuals and networks, not an entire ethnic population.
The latest allegations nevertheless demonstrate how extremist propaganda can continue to influence individuals long after the territorial defeat of ISIS in Iraq and Syria.
Kash Patel Highlights FBI’s Counterterrorism Results
FBI Director Kash Patel praised the operation following Mohamud’s arrest, describing it as another example of federal investigators intervening before a terrorist threat could become a national tragedy.
“This individual allegedly obtained a weapon he hoped to use in a mass casualty attack in support of ISIS, but this FBI arrested him and put a stop to his plans,” Patel said in an October 7 Justice Department announcement.
Patel also highlighted the bureau’s broader counterterrorism record, citing more than 1,100 individuals prevented from conducting attacks and over 4,000 foreign terrorist organization-related disruptions and arrests.
Those figures, which Patel said represented a 38% increase, have become part of the administration’s argument that its national security strategy is producing results. The Justice Department announcement did not provide enough comparative detail to independently evaluate all the figures.
The operation itself also underscores the importance of sustained intelligence work.
Investigators maintained contact with Mohamud through confidential sources, monitored his communications, and ultimately arranged a controlled weapons transaction.
Importantly, the rifle supplied by the FBI had been rendered inoperable before the exchange.
The distinction matters because authorities were able to document the alleged suspect’s intentions without placing a functioning rifle into his hands.
Suspect Allegedly Considered Fighting Overseas Before Targeting Americans
Perhaps the most alarming aspect of the case is how Mohamud’s alleged ambitions evolved.
Federal investigators say he initially wanted to travel to Somalia and join al-Shabaab.
In May, he reportedly expressed enthusiasm about leaving the United States, telling a source he was “so excited to make hijrah.”
But international travel required money he apparently did not have.
According to prosecutors, Mohamud repeatedly discussed launching an attack in Minnesota if he could not afford to leave the country.
By July, his communications had reportedly shifted toward a mass shooting at the Mall of America.
Investigators say he expressed antisemitic hostility, falsely assumed the shopping center was Jewish-owned in a way that justified targeting it, and discussed killing between 30 and 60 people.
He also allegedly referenced previous mass-casualty attacks, including the 2016 Pulse nightclub shooting in Orlando and the 2025 New Orleans terrorist attack.
The progression from aspiring foreign fighter to alleged domestic attacker presents a serious challenge for counterterrorism authorities.
An individual does not necessarily need to travel overseas, receive military training, or establish direct operational contact with ISIS leadership to become dangerous.
Extremist propaganda, personal radicalization, and access to weapons can create a threat much closer to home.
Renewed Questions for Minnesota’s Political Leadership
The case is also likely to intensify political scrutiny of Minnesota Governor Tim Walz and the state’s response to extremist recruitment.
Conservatives have long argued that public officials must treat domestic radicalization as a central security concern rather than allowing political disputes over immigration and community relations to distract from credible threats.
Minnesota’s documented history of terrorist recruitment makes the issue particularly urgent.
However, the investigation began in December 2024, and the available court documents do not establish that Walz’s policies caused Mohamud’s alleged radicalization or that state officials knowingly ignored this specific plot.
The central question for policymakers is whether local authorities, community organizations, and federal investigators have sufficient resources and coordination to identify potential attackers early.
In this instance, the federal investigation appears to have achieved precisely that objective.
A Potential Massacre Prevented, but the Threat Remains
Mohamud was arrested on October 6 and made his initial federal court appearance the following day.
He faces a charge of knowingly receiving a firearm and ammunition for the purpose of committing a federal terrorism offense.
The allegations describe an attack that could have transformed a family-oriented cultural gathering into a scene of devastating violence.
Instead, investigators intervened before the scheduled event.
President Donald Trump praised the FBI’s performance, saying, “The FBI did a great job.”
The arrest represents a significant counterterrorism success, but it also serves as a warning about the continuing appeal of ISIS propaganda to vulnerable and radicalized individuals inside the United States.
For families planning to attend the October 24 celebration, the outcome could hardly have been more consequential.
A suspect allegedly preparing to kill dozens of innocent people is now in federal custody, and a potentially catastrophic attack has been prevented.
The larger challenge remains: ensuring that the next extremist plotting violence is identified before innocent Americans become targets.
