A federal judge ruled Wednesday there is sufficient evidence to proceed with a hate crime case against a man accused of injuring more than a dozen people after lobbing Molotov cocktails at people in Boulder, Colorado who were supporting Israeli hostages in Gaza.

Fifteen people ages 52 to 88 were injured with burns ranging from serious to minor when Mohamed Sabry Soliman, 45, allegedly launched the attack, authorities say. He lived in Colorado Springs, Colorado, after coming to the U.S. on a tourist visa in late 2022 and staying after it expired.

Soliman faces a maximum sentence of life in prison if he's found guilty of the federal hate crime charges against him. The native of Egypt has also been charged in state court with 118 criminal counts, including attempted murder and other offenses. He sat expressionless in federal court in Denver.

Soliman is accused of lobbing Molotov cocktails and using a makeshift flamethrower to target Run for Their Lives, a group advocating for the release of Israeli hostages taken by Hamas and held in Gaza for more than 20 months.
