Two Montclair men and a Washington state man have pleaded guilty to terrorism-related offenses for supporting the Islamic State of Iraq and al Sham, or ISIS, federal prosecutors said.

Tomas-Kaan Jimenez-Guzel, 19, pleaded guilty Monday to conspiracy to provide material support to a designated foreign terrorist organization. Milo Sedarat, 21, pleaded guilty Tuesday to concealing material support and resources to a designated foreign terrorist organization, according to the U.S. Attorney's Office for the District of New Jersey.

A third defendant, Saed Ali Mirreh, 20, of Kent, Washington, pleaded guilty July 22 in federal court in Seattle to conspiracy to provide material support to a designated foreign terrorist organization. Prosecutors said his case was transferred from New Jersey to Washington so he could enter his plea.

According to court documents and statements made in court, the three men and other co-conspirators communicated through encrypted messaging apps between July and November 2025 and agreed to travel to Turkey before continuing to Syria to join ISIS as fighters.

Prosecutors said Sedarat gave Jimenez-Guzel $500 in cash in October 2025 to help pay for Mirreh's plane ticket and instructed him not to bring his cellphone to the meeting. Jimenez-Guzel later transferred the money to Mirreh, according to prosecutors.

After several individuals in Dearborn, Michigan, were arrested Oct. 31, 2025, in connection with an alleged ISIS-inspired attack plot, prosecutors said Jimenez-Guzel, Mirreh and their co-conspirators moved up their travel plans.

Jimenez-Guzel was arrested Nov. 4, 2025, after arriving at Newark Liberty International Airport for a flight to Istanbul, Turkey. Mirreh was arrested later that day at his home in Washington, prosecutors said.

Mirreh is scheduled to be sentenced Oct. 16. Sedarat is scheduled for sentencing Dec. 2, and Jimenez-Guzel is scheduled to be sentenced Dec. 3.

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