Two Montclair, New Jersey men and a Washington state man have pleaded guilty to federal terrorism-related charges stemming from a conspiracy to support the Islamic State of Iraq and al Sham (ISIS), the U.S. Attorney’s Office for the District of New Jersey announced Wednesday.

Tomas-Kaan Jimenez-Guzel, 19, pleaded guilty to conspiracy to provide material support to a designated foreign terrorist organization. Milo Sedarat, 21, pleaded guilty to concealing material support to a designated foreign terrorist organization. Both entered their guilty pleas this week in U.S. District Court in Newark.

A third defendant, Saed Ali Mirreh, 20, of Kent, Washington, pleaded guilty on July 22 in federal court in Seattle after consenting to have his New Jersey case transferred there for the purpose of entering his plea. He admitted to conspiracy to provide material support to ISIS.

According to federal prosecutors, the conspiracy took place between July and November 2025. Investigators said the defendants communicated through encrypted messaging applications and planned to travel to Turkey before continuing into Syria to join ISIS as fighters.

Authorities said Sedarat provided Jimenez-Guzel with $500 in cash to help purchase Mirreh’s airline ticket. Prosecutors said Sedarat intentionally used cash and instructed Jimenez-Guzel not to bring his cellphone to the meeting in an effort to conceal the transaction. Jimenez-Guzel later transferred the money to Mirreh.

Federal investigators said Jimenez-Guzel purchased a ticket from Newark Liberty International Airport to Istanbul, while Mirreh booked a flight from Seattle to Turkey. After several associates in Dearborn, Michigan were arrested in connection with an alleged ISIS-inspired attack plot, prosecutors said the group accelerated its travel plans.

Jimenez-Guzel rebooked his flight to depart on November 5, 2025, and Mirreh also booked an earlier flight that same day. Jimenez-Guzel was arrested after arriving at Newark Liberty International Airport on November 4, 2025, while Mirreh was arrested later that evening at his home in Washington.

U.S. Attorney Robert Frazer said his office remains committed to disrupting foreign terrorist organizations and prosecuting anyone who provides support to them. FBI Newark Special Agent in Charge Stefanie Roddy said investigators prevented the defendants from traveling overseas to fight for ISIS and emphasized that law enforcement will continue to aggressively pursue those who support terrorist organizations.

The conspiracy charge carries a maximum sentence of 20 years in federal prison, a $250,000 fine, and lifetime supervised release. The concealment charge carries a maximum sentence of 10 years in prison, a $250,000 fine, and lifetime supervised release.

Mirreh is scheduled to be sentenced on October 16, 2026. Sedarat is scheduled for sentencing on December 2, 2026, and Jimenez-Guzel is scheduled for sentencing on December 3, 2026.
