MINNESOTA (KAAB TV) – Federal authorities have arrested a 23-year-old Somali man residing in Minnesota after uncovering evidence that he attempted to join the Islamic State (ISIS), praised deadly terrorist attacks, and expressed a willingness to carry out violence against the United States.
The suspect, identified as Abdisatar Ahmed Hassan, was taken into custody following a multi-agency investigation led by the FBI’s Joint Terrorism Task Force.
According to prosecutors, Hassan attempted on two occasions to travel to Somalia in an effort to join ISIS, and repeatedly used social media to express support for the terrorist organization and its violent ideology.
Deputy U.S. Attorney Joe Thompson, who is prosecuting the case, made a strong statement following the arrest:
“Abdisatar Hassan proudly filmed himself with the ISIS flag and celebrated terrorist attacks against his own country. We will not allow Minnesota to become a breeding ground or safe haven for extremists who seek to harm the United States.”
Social Media Activity Raised Red Flags
Authorities became aware of Hassan’s activities through disturbing content he posted online.
Investigators say that his social media accounts were used to glorify ISIS and other terrorist organizations, including Al-Shabaab, a Somalia-based jihadist group that has been designated a foreign terrorist organization by the U.S. government.
One particularly concerning post referenced the January 1, 2025 terrorist attack in New Orleans, which resulted in the deaths of 14 innocent people. Hassan referred to the attacker as a “hero” and used celebratory language to describe the tragedy.
In February 2025, Hassan posted a video of himself holding a homemade black ISIS flag in his home — an act which further heightened concern among federal investigators.
Digital Evidence Revealed Explosive Materials and Instructions
When FBI agents executed a search warrant, they seized Hassan’s mobile devices. Forensic analysis of the phones uncovered a series of encrypted messages and alarming PDF documents written in both French and Arabic.
These files reportedly included detailed instructions for constructing and detonating explosives — raising serious concerns about Hassan’s intentions and operational capabilities.
The FBI also found message exchanges between Hassan and a person believed to be a journalist or media contact. Authorities have not disclosed whether that individual is under investigation.
Confession and Awaiting Sentencing
During a recent court appearance, Hassan admitted to the charges and confirmed that he had intended to travel overseas to join ISIS and support its mission.
His sentencing hearing is expected to take place in the coming weeks. He faces a lengthy prison sentence under federal anti-terrorism statutes.
FBI Reaffirms National Security Priorities
Alvin M. Winston Sr., Special Agent in Charge of the FBI’s Minneapolis Division, praised the work of the agents and analysts involved in the case:
“Today’s arrest and forthcoming sentencing are the results of countless hours of investigative work by the FBI and our partners. Keeping Minnesota — and the rest of the United States — safe from foreign terrorist organizations like ISIS and Al-Shabaab remains one of our highest priorities. These groups continue to pose a credible threat to national security.”
This case underscores the ongoing threat posed by online radicalization and domestic sympathizers of foreign terrorist organizations. The Department of Justice and FBI continue to urge the public to report suspicious behavior and online activity to law enforcement.
