A Colorado man has been charged with federal hate crimes for alleged bomb attacks in a pro-Israeli rally in Boulder, according to an affidavit issued by the U.S. Department of Justice.

Mohamed Sabry Soliman has faced a series of state charges, including attempted murder, following Sunday's attack on Boulder in Boulder City, which seeks to draw attention to the hostages attacked by Hamas in 2023 on Israel.

U.S. Attorney General Pam Bondi said the suspects will be held responsible for the so-called "anti-Semitism terrorist attacks" to the maximum extent of the law.

Soliman, 45, has planned for more than a year of attacks, the affidavit said. Investigators found 14 Molotov cocktails containing gasoline or gasoline, and nearby suspects were detained.

Police also found his car parked in a nearby gasoline can in his car, with a gasoline herbicide sprayer on the scene. Soriman told investigators that he learned how to make firebombs from YouTube.

The affidavit quoted videos posted on social media during the attack, showing Soliman "walked shirtless, walking back and forth while lifting up what appeared to be a Molotov cocktail".

The affidavit said the suspect was detained in lieu of $10 million in bail, and according to official records, he told police that he "wanted to kill all Zionists and hoped they were all dead."

In a four-block area in downtown Boulder, violence at the popular Pearl Street Pedestrian Mall unfolds against the backdrop of Israel’s war on Gaza, which continues to spark global tensions and has fought against competition in the U.S. anti-Semitic violence.

The attack took place at the beginning of the Jewish holiday, Shavuot's sign was reading the Torah, and just a week later, a man also shouted "Free Palestine" and was accused of fatally shooting two Israeli embassy staff outside the Jewish Museum in Washington.

“Millions of people like this”

According to the complaint, Soliman lives in Colorado Springs with his wife and five children, a city located about 161 kilometers (100 miles) south of Boulder. The affidavit says he waited until his daughter graduated and attacked.

There are few other details about him.

Todd Lyons, acting director of U.S. immigration and customs enforcement, said Soliman overdue his tourist visa and obtained an expired work permit.

Federal documents do not mention his nationality, but the New York Times said he was Egyptian, citing the Department of Homeland Security.

The Department of Homeland Security and Justice did not respond to a request for comment. The FBI Denver office, which is handling the case, did not immediately respond to emails or phone calls for details of the case.

Officials from the Boulder County Jail, Boulder Police and Boulder County Sheriff’s Office did not immediately respond to the investigation.

"There are millions of people like this who try to find people from past administrations who have not been properly screened," Lyons said at a press conference in Boston. "I will tell you that this is the ice's huge effort right now."

Under former U.S. President Joe Biden, ICE prioritizes arrests of serious criminals and calls on officials to consider humanitarian factors when arresting.

Lyon declined to provide more information, but a spokesman for the Department of Homeland Security had previously said Soliman entered the country in August 2022 and applied for asylum next month. "The suspect Mohamed Soliman is illegal in our country," the spokesman said.

President Donald Trump criticized Biden for the incident.

"Yesterday's terrorist attack on Boulder, Colorado will not be tolerated," Trump said on his truth social network.

He accused Biden of a ridiculous open border policy of allowing Soliman to enter the country.

"This is another example of what we must ensure borders are safe and expel illegal anti-American activists from our homeland," he wrote.

Boulder police said four women and four men aged 52 to 88 were taken to the hospital after the attack. Four other victims were confirmed on Monday.

The attack took place at the Pearl Street Mall in the popular pedestrian shopping district near the University of Colorado, an event held by Run for their lifetime, and the group is committed to drawing attention to the hostages after the 2023 2023 attack on Israel.

Rabbi Yisroel Wilhelm, Chabad director of the University of Colorado Boulder, told CBS Colorado that the 88-year-old victim was a massacre refugee fleeing Europe.

Sunday’s attack wasn’t the first time Boulder’s striking mass violence, a college town that attracts many young professionals and outdoor enthusiasts. In 2021, a gunman fatally shot and killed 10 people, including a policeman at a local supermarket.
