Egyptian Islamic terrorist Mohamed Sabry Soliman was sentenced Thursday to spend the rest of his life behind bars without the possibility of parole after admitting to a deadly firebombing attack at a gathering in Boulder, Colorado aimed at spreading awareness of then-hostage Israelis held in Gaza by Hamas.

The 46-year-old man, who federal officials say was residing illegally in the United States, pleaded guilty to dozens of felony offenses in state court, among them two first-degree murder charges that each carry automatic life sentences.

Prosecutors said Soliman attacked participants at a June 2025 rally supporting Israelis held hostage by Hamas terrorists in Gaza by throwing Molotov cocktails into the crowd gathered at a downtown Boulder pedestrian mall.

Karen Diamond Hy’d, 82, suffered severe injuries in the attack and later died. Another 12 people were wounded.

According to investigators, Soliman had allegedly prepared for the assault for about a year and was motivated by a desire “to kill all Zionist people.”

During Thursday’s hearing, Soliman mostly stared downward at the defense table. He still faces separate federal hate crime charges, to which he has pleaded not guilty. Federal prosecutors are reportedly weighing whether to seek the death penalty.

Speaking through an interpreter, Soliman expressed remorse to the victims and addressed Diamond’s death directly.

“There are no words that can express my sadness for her passing,” Soliman says.

He told the court he was not asking for mercy and urged federal authorities not to seek execution in the pending federal case.

“If I went back, I would not have done this as this is not according to the teaching of Islam,” Soliman says. “What I did came out of myself and only myself.”

Earlier in the proceedings, a prosecutor read a statement from Diamond’s sons, who said Soliman should “not be allowed to see his family again since he is responsible for our mother never seeing her family again.”
