The Federal Bureau of Investigation (FBI) identified Mohamed Sabry Soliman as the man who shouted “free Palestine” as he attacked a march in Boulder Colorado on Sunday.

Six victims, aged 67 to 88, were transported to local hospitals after Soliman used a “makeshift flamethrower” and hurled “an incendiary device” into the crowd.

Four of the victims of the attack were taken to Boulder Community Hospital, and two others were airlifted to the Aurora Hospital Burn Unit. All six victims are still being treated, with one listed was seriously injured while the others received more minor injuries, according to police.

A senior White House official told Newsweek that President Donald Trump “has been briefed” on the attack.

The Context

Solimon, 45, had attacked the American Jewish group Run for Their Lives, which organizes events while calling for the immediate release of the hostages held by Hamas, according to their website.

He injured several people at the Pearl Street Mall in Boulder, Colorado, with the extent of injuries unconfirmed but ranging from minor to more severe, according to local law enforcement. The suspect was injured as well.

FBI Director Kash Patel in a post on X referred to the attack as a “targeted terror attack,” but Boulder Police Chief Stephen Redfearn at an earlier press briefing said “it would be irresponsible for me to speculate on motive this early on.”

What To Know

At the briefing on Sunday evening, FBI Special Agent McCullough said that the agency had determined based on preliminary facts that Soliman carried out a “targeted attack” and that the agency would investigate the attack as an act of terrorism.

Soliman was heard shouting “Free Palestine” during the attack, McCullough told reporters.

McCullough said that nothing at this time tied Soliman to a wider network, but that the agency and partners would carry out a thorough investigation, refusing to state what charges Soliman would face until that investigation had concluded.

Redfearn, who also attended the briefing, said that the police believe there is no other suspect at large and that they have the sole suspect in custody. He thanked the various law enforcement agencies cooperating with his police department, as well as first responders.

“I can’t thank our partners enough,” Redfearn said. “Also I would be remiss if I didn’t mention the first responders today: When this call came in today, our officers rushed as quickly as they could somewhere close to the area, and they immediately ran into a chaotic situation where a man was throwing Molotov cocktails and using other devices to hurt people.”

“Our officers, as they’re trained, immediately interacted with the suspect took him into custody and began rendering aid to those victims, and I’m very proud of our response to their very proud of our partners as well with the fire department as well as American Medical response,” Redfearn said, adding that Boulder is no stranger to tragedy but that the city “will again recover.”

Law enforcement appealed for any video footage of the attack be sent to fbi.gov/boulderattack to assist in the investigation.

What People Are Saying

Colorado Governor Jared Polis wrote on X: “As the American Jewish community continues to reel from the horrific antisemitic murders in Washington, D.C., it is unfathomable that the Jewish community is facing another terror attack here in Boulder, on the eve of the holiday of Shavuot no less. Several individuals were brutally attacked while peacefully marching to draw attention to the plight of the hostages who have been held by Hamas terrorists in Gaza for 604 days. I condemn this vicious act of terrorism, and pray for the recovery of the victims.”

FBI Deputy Director Dan Bongino wrote on X: “FBI personnel are on the scene in Boulder, Colorado, along with local law enforcement. We are investigating this incident as an act of terror, and targeted violence. All of the necessary assets will be dedicated to this investigation. If you have any investigative tips please contact the FBI. And if you aided or abetted this attack, we will find you. You cannot hide.”

Danny Danon, Permanent Representative of Israel to the United Nations, wrote on X: “Terrorism against Jews does not stop at the Gaza border – it is already burning the streets of America. Today, in Boulder, Colorado, Jewish people marched with a moral and humane demand: to return the hostages. In response, the Jewish protesters were brutally attacked, with an attacker throwing a Molotov cocktails at them. Make no mistake – this is not a political protest, this is terrorism. The time for statements is over. It is time for concrete action to be taken against the instigators wherever they may be.”

What Happens Next

The FBI, Boulder police, and other partner agencies will continue to gather evidence to provide a robust review of the incident and determine a motive.

Boulder County District Attorney Michael Dougherty and the U.S. Department of Justice will also work together over the coming days to determine appropriate charges.
