BOULDER: A man with a makeshift flamethrower yelled “Free Palestine” and threw an incendiary device into a group that had assembled to raise attention for Israeli hostages in Gaza, law enforcement officials said Sunday. Six people were injured, some with burns.
The suspect, Mohamed Sabry Soliman, 45, was expected to face charges in connection with the attack the FBI was investigating as a terrorist act.
The burst of violence at the popular Pearl Street pedestrian mall, a four-block area in downtown Boulder, unfolded against the backdrop of a war between Israel and Hamas that continues to inflame global tensions and has contributed to a spike in antisemitic violence in the United States. It occurred barely a week after a man who also yelled “Free Palestine” was charged with fatally shooting two Israeli embassy staffers outside of a Jewish museum in Washington.

“Sadly, attacks like this are becoming too common across the country,” said Mark Michalek, the special agent in charge of the FBI’s Denver field office, which encompasses Boulder. “This is an example of how perpetrators of violence continue to threaten communities across the nation.”
The six victims who were wounded range in age from 67 to 88 and the injuries spanned from serious to minor, officials said.
The attack occurred as people with a volunteer group called Run For Their Lives was concluding their weekly demonstration to raise visibility for the hostages who remain in Gaza. Video from the scene shows a witness shouting, “He’s right there. He’s throwing Molotov cocktails,” as a police officer with his gun drawn advances on a bare-chested suspect who is holding containers in each hand.
Lynn Segal, 72, was among about 20 people who gathered Sunday. They had finished their march in front of the courthouse when a “rope of fire” shot in front of her and then “two big flares.”
She said the scene quickly turned chaotic as people worked to find water to put out flames and find help.
Segal, who said she is Jewish on her father’s side and has supported Palestine for more than 40 years, was concerned that she might be accused of helping the suspect because she was wearing a pro-Palestine shirt.
“There were people who were burning, I wanted to help,” she said. “But I didn’t want to be associated with the perpetrator.”
Authorities did not disclose details about Soliman but said they believe that he acted alone and that no other suspect was being sought. No criminal charges were immediately announced but officials said they would move to hold Soliman accountable. He was also injured and was taken to the hospital to be treated, but authorities didn’t elaborate on the nature of his injuries.
FBI leaders immediately declared the attack an act of terrorism and the Justice Department denounced it as a “needless act of violence, which follows recent attacks against Jewish Americans.”
“This act of terror is being investigated as an act of ideologically motivated violence based on the early information, the evidence, and witness accounts. We will speak clearly on these incidents when the facts warrant it,” FBI Deputy Director Dan Bongino said in a post on X.
Israel’s military campaign on Gaza has killed over 54,000 people, mostly women and children, according to Gaza’s Health Ministry, which does not say how many of the dead were civilians or combatants. The offensive has destroyed vast areas, displaced around 90 percent of the population and left people almost completely reliant on international aid.
The violence comes four years after a shooting rampage at a grocery store in Boulder, about 25 miles (40 kilometers) northwest of Denver, that killed four people. The gunman was sentenced to life in prison for murder after a jury rejected his attempt to avoid prison time by pleading not guilty by reason of insanity.
Multiple blocks of the pedestrian mall area were evacuated by police. The scene shortly after the attack was tense, as law enforcement agents with a police dog walked through the streets looking for threats and instructed the public to stay clear of the mall.
