An Egyptian man who firebombed a Jewish group at a demonstration in Boulder last year has pleaded guilty to federal hate crimes and other charges.

Mohamed Soliman is already serving life in prison after pleading guilty to state charges last spring in connection with the deadly June 2025 attack on elderly activists. He yelled “Free Palestine!” and threw two Molotov cocktails at a group demonstrating in support of hostages taken in the Oct. 7, 2023, Hamas attack on Israel.

Soliman used a “makeshift flamethrower and threw an incendiary device” into the crowd, the FBI said.

Federal prosecutors accused Soliman of attacking the group because they were Jewish. The flames badly burned Karen Diamond, 82, and injured a dozen others. Diamond died three weeks later and her family said she suffered “indescribable pain.”
