A man in Boulder disguised himself as a gardener and attacked a group of demonstrators, injuring 12 people during their weekly protest for the release of Israeli hostages in Gaza. Authorities report that his initial plan was to kill the entire group, but he seemed to reconsider.

Identified as Mohamed Sabry Soliman, the attacker possessed 18 Molotov cocktails but only threw two, yelling “Free Palestine” as he did so. According to police, he refrained from executing his full plan because he became scared and had no prior experience with violence.

Even with just two devices thrown, over half of the 20-person group was wounded. Officials noted that Soliman showed no remorse for his actions.

The 45-year-old Soliman — whose first name also was spelled Mohammed in some court documents — planned the attack for more than a year and specifically targeted what he described as a “Zionist group,” authorities said in court papers charging him with a federal hate crime.

“When he was interviewed about the attack, he said he wanted them all to die, he had no regrets and he would go back and do it again,” Acting U.S. Attorney J. Bishop Grewell for the District of Colorado said during a news conference Monday.

Federal and state prosecutors filed separate criminal cases against Soliman, charging him with a hate crime and attempted murder, respectively. He faces additional state charges related to the incendiary devices, and more charges are possible in federal court, where the Justice Department will seek a grand jury indictment.

Soliman is being held on a $10 million, cash-only bond, prosecutors said. His next court hearing is set for Thursday.

An FBI affidavit says Soliman told the police he was driven by a desire “to kill all Zionist people,” a reference to the movement to establish and protect a Jewish state in Israel.

Soliman’s attorney, public defender Kathryn Herold, declined to comment after the hearing.

Soliman was living in the U.S. illegally after entering the country in August 2022 on a B2 visa that expired in February 2023, Department of Homeland Security Assistant Secretary Tricia McLaughlin said in a post on the social platform X.

The burst of violence at the popular Pearl Street pedestrian mall in downtown Boulder unfolded against the backdrop of the Israel-Hamas war, which continues to inflame global tensions and has contributed to a spike in antisemitic violence in the United States. The attack happened on the beginning of the Jewish holiday of Shavuot and barely a week after a man who also yelled “Free Palestine” was charged with fatally shooting two Israeli Embassy staffers outside a Jewish museum in Washington.

Six victims hospitalized

The victims who were wounded range in age from 52 to 88, and the injuries spanned from serious to minor, officials said.

Six of the injured were taken to hospitals, and four have since been released, said Miri Kornfeld, a Denver-based organizer connected to the group. She said the clothing of one of those who remains hospitalized caught on fire.

Members of the volunteer group called Run For Their Lives were holding their weekly demonstration when the attack happened. Video from the scene captured by witness Alex Osante of San Diego shows people pouring water on a woman lying on the ground who Osante said had caught fire during the attack.

Molotov cocktails found

Osante said that after the suspect threw the two incendiary devices, apparently catching himself on fire as he threw the second, he took off his shirt and what appeared to be a bulletproof vest before police arrived. The man dropped to the ground and was arrested without any apparent resistance in the video Osante filmed.

The Molotov cocktails were made up of glass wine carafe bottles or jars with clear liquid and red rags hanging out of the them, the FBI said.

“He stated that he had been planning the attack for a year and was waiting until after his daughter graduated to conduct the attack,” the affidavit says.

He had gas in a backpack sprayer but told investigators he didn’t spray it on anyone but himself “because he had planned on dying.”

Soliman also told investigators he took a concealed carry class and tried to buy a gun but was denied because he is not a legal U.S. citizen.

Suspect hospitalized after attack

Authorities said they believe Soliman acted alone. He was also injured and taken to a hospital. Authorities did not elaborate on the nature of his injuries, but a booking photo showed him with a large bandage over one ear.

Soliman, who was born in Egypt, moved three years ago to Colorado Springs, where he lived with his wife and five kids, according to state court documents. He previously spent 17 years living in Kuwait.

McLaughlin said Soliman filed for asylum in September 2022 and was granted a work authorization in March 2023 that had expired. DHS did not respond to requests for additional information.
