A 19-year-old from Kent has been charged with conspiring to support ISIS after being arrested by the FBI.
According to a criminal complaint, Saed Ali Mirreh was arrested at his home on Tuesday. It was the same day his alleged co-conspirator was detained at Newark Liberty International Airport in New Jersey.
Federal prosecutors allege that Mirreh and others used encrypted messaging apps to coordinate travel from the United States to Turkey, with plans to cross the border into Syria to join ISIS as fighters. After his arrest, court documents say Mirreh admitted to purchasing a ticket from Seattle-Tacoma International Airport to Istanbul for mid-November.
Special Agent in Charge of the FBI Seattle field office, W. Mike Herrington, said in a statement:
“I commend the outstanding work and dedication displayed over the past week by all in FBI Seattle, and other field offices across the country, who played an important role in preventing a potential attack and keeping our communities safe. This is a top priority for the FBI in the state of Washington, and our Joint Terrorism Task Force remains vigilant, working behind the scenes with our partners to protect our nation from threats, both foreign and domestic.”
Link to Michigan Terrorist Plot Investigation
The federal complaint also connects Mirreh to individuals in Dearborn, Michigan, who were arrested on October 31, 2025, for allegedly planning an ISIS-inspired attack. After those arrests, Mirreh and his co-conspirators allegedly accelerated their travel plans, rebooking flights to leave the United States earlier than planned.
According to court documents, Mirreh had “referred to himself as the ‘finance guy’ for the other co-conspirators who are traveling,” and raised the money through internet scams.
On the FBI’s Radar Since 2023
Investigators say Mirreh was first identified by the FBI in 2023, when agents executed a search warrant at his Kent home. At the time, Mirreh, who was a minor, had been communicating online about potential ISIS-inspired attacks in the United States and providing support to a Canadian juvenile later arrested on terrorism charges.
During interviews in 2023 and 2024, Mirreh admitted to sharing extremist propaganda but denied any intent to carry out violence. However, by mid-2025, agents say he had reconnected with ISIS supporters and resumed posting extremist content online.
According to the affidavit, Mirreh’s Instagram account was found to be in contact with at least three overseas ISIS affiliates. He allegedly discussed “jihad against the kuffar,” shared photos of weapons and tactical gear, and posted a video of himself wearing body armor and shouting “Allahu Akbar” inside a car with what appeared to be a gun case next to him.
Federal Charges and Next Steps
Mirreh is charged with conspiracy to provide material support to a designated foreign terrorist organization. He faces a potential sentence of up to 20 years in federal prison if convicted.
