U.S. Citizen Who Fought for ISIS Pleads Guilty to Receiving Military Training from a Foreign Terrorist Organization

WASHINGTON -- Lirim Sylejmani, 48, a Kosovo-born naturalized U.S. citizen, pleaded guilty today in U.S. District Court in Washington D.C., to receiving military training from the Islamic State of Iraq and al-Sham (ISIS), a designated foreign terrorist organization.

The plea was announced by U.S. Attorney Matthew M. Graves, Assistant Attorney General Matthew G. Olsen of the Department of Justice's National Security Division, and FBI Special Agent in Charge Sanjay Virmani of the Washington Field Office Counterterrorism Division.

"As the threat from terrorist groups such as ISIS persists, we will continue to work aggressively with our law enforcement partners to bring those who would seek to join and receive training from these groups to justice," said U.S. Attorney Graves. "This prosecution demonstrates that those who seek to support terrorism will pay a heavy price."

According to court documents, from November 2015 through February 2019, Sylejmani received military training from ISIS in Syria. Sylejmani was captured by the Syrian Democratic Forces (SDF) in 2019, and spoke to a number of media outlets about his time with ISIS.

In November 2015, Sylejmani, a naturalized U.S. citizen living in Kosovo, decided to travel to Syria with his family to join ISIS. After entering Syria, Sylejmani completed his ISIS intake process. He adopted the name Abu Sulayman al-Kosovi and trained to be a soldier with other ISIS recruits. Sylejmani' s military training included instruction on how to assemble and fire an AK-47 rifle, as well as how to use a PK Machine gun, M-16 rifle and grenades.

Upon completion of the 21-day military training, ISIS assigned Sylejmani to a battalion in Mosul, Iraq, and issued him an AK-47, four AK-47 magazines, a belt to hold the magazines and two grenades. Sylejmani pledged "bayat"(allegiance) to Abu Bakr Al-Baghdadi, the leader of ISIS, and to the ISIS organization, in front of an Iraqi ISIS member. In May 2016, the defendant reported for ribat (guard) duty on the front line of the Manbij offensive. The defendant brought his gun belt, AK-47 and magazines to his ribat assignment. During a battle with Coalition Forces he was hit with shrapnel in his legs. After receiving these injuries, he eventually was reassigned to a new battalion in the fall of 2017. Sylejmani also received payments from ISIS for his services. Between November 2017 and February 2019, Sylejmani moved his family southeast to Baghouz, Syria, as the territorial Caliphate of ISIS collapsed.

On February 27, 2019, Sylejmani and his family were captured by Coalition Forces. Sylejmani was jailed by the SDF in Syria at the Dashisha prison. He was transferred to United States law enforcement personnel on September 15, 2020, to face criminal charges in the District of Columbia.

This case is the result of an investigation conducted by the FBI's Joint Terrorism Task Force.

This case is being prosecuted by Assistant U.S Attorneys Brenda J. Johnson, Steven Wasserman and Kimberly Paschall of the National Security Section, and Trial Attorney Jennifer Levy of the National Security Division's Counterterrorism Section.
