A naturalized U.S. citizen who pleaded guilty to receiving military training from the Islamic State in Syria was sentenced on Monday to 10 years in federal prison.

Lirim Sylejmani, 49, who was born in Kosovo and moved to Chicago about 25 years ago, engaged in at least one battle against U.S.-led coalition forces after he entered Syria a decade ago, according to prosecutors.

U.S. District Judge Rudolph Contreras in Washington, D.C., handed down Sylejmani’s prison sentence, which will be followed by a lifetime of supervised release.

Sylejmani pleaded guilty in December to one count of receiving military training from a foreign terrorist organization.

His 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.

Sylejmani was also once injured in a battle with Syrian forces in June 2016.

Prosecutors said Sylejmani, who adopted the name Abu Sulayman al-Kosovi, pledged “bayat,” or allegiance, to ISIS leader Abu Bakr Al-Baghdadi and to the ISIS organization in front of an Iraqi ISIS member.

He was transferred to the U.S. in September 2020 to face criminal charges in Washington, D.C.

“The conduct is far more than a single, impulsive act. He chose to jeopardize the safety of his family by bringing them to a war-torn country to join and take up arms for ISIS,” prosecutors wrote.

Sylejmani’s attorneys claim he is not a “committed jihadist” and does not espouse violence.

“He is guilt-ridden for his actions and the harm he has visited on his family, who remain detained in a refugee camp in Syria living under terrible conditions,” his lawyers wrote. “He wishes only to complete his time and find his wife and children, so he can live an average law-abiding life with them.”
