BOULDER, Colorado 鈥 Eight people were injured on Sunday when a 45-year-old man yelled 鈥淔ree Palestine鈥 and threw incendiary devices into a crowd in Boulder, Colorado where a demonstration to remember the Israeli hostages who remain in Gaza was taking place, authorities said.

Four women and four men between 52 and 88 years old were transported to hospitals, Boulder police said. Authorities had earlier put the count of the injured at six and said at least one of them was in critical condition.

鈥淎s a result of these preliminary facts, it is clear that this is a targeted act of violence and the FBI (Federal Bureau of Investigation) is investigating this as an act of terrorism,鈥 the FBI special agent in charge of the Denver Field Office, Mark Michalek, said.

Mr. Michalek named the suspect Mohamed Soliman, who was hospitalized shortly after the attack. Reuters could not immediately locate contact information for him or his family.

FBI Director Kash Patel also described the incident as a 鈥渢argeted terror attack,鈥 and Colorado Attorney General Phil Weiser said it appeared to be 鈥渁 hate crime given the group that was targeted.鈥 Boulder Police Chief Stephen Redfearn said he did not believe anyone else was involved.

鈥淲e鈥檙e fairly confident we have the lone suspect in custody,鈥 he said.

The attack took place on the Pearl Street Mall, a popular pedestrian shopping district in the shadow of the University of Colorado, during an event organized by Run for Their Lives, an organization devoted to drawing attention to the hostages seized in the aftermath of Hamas鈥 2023 attack on Israel.

In a statement, the group said the walks have been held every week since then for the hostages, 鈥渨ithout any violent incidents until today.鈥

Israeli Prime Minister Benjamin Netanyahu said in a statement that the victims were attacked 鈥渟imply because they were Jews鈥 and that he trusted US authorities would prosecute 鈥渢he cold blood perpetrator to the fullest extent of the law.鈥

鈥淭he antisemitic attacks around the world are a direct result of blood libels against the Jewish state and people, and this must be stopped,鈥 he said.

The incident comes amid heightened tensions in the United States over Israel鈥檚 war in Gaza, which has spurred both an increase in antisemitic hate crime as well as moves by conservative supporters of Israel, led by President Donald J. Trump, to brand pro-Palestinian protests as antisemitic. His administration has detained protesters of the war without charge and cut off funding to elite US universities that have permitted such demonstrations.

In a post to X, a social network, Mr. Trump鈥檚 Deputy Chief of Staff Stephen Miller said Mr. Soliman had overstayed his visa and been allowed to work by the previous administration. He said it was further evidence of the need to 鈥渇ully reverse鈥 what he described as 鈥渟uicidal migration.鈥

Reuters was not able to independently verify the suspect鈥檚 immigration status. When asked about Soliman, the Department of Homeland Security said more information would be provided as it became available.

VICTIMS BURNED
Brooke Coffman, a 19-year-old at the University of Colorado who witnessed the Boulder incident, said she saw four women lying or sitting on the ground with burns on their legs. One of them appeared to have been badly burned on most of her body and had been wrapped in a flag by someone, she said.

She described seeing a man whom she presumed to be the attacker standing in the courtyard shirtless, holding a glass bottle of clear liquid and shouting.

鈥淓verybody is yelling, 鈥榞et water, get water,鈥欌 Coffman said.

Senate Minority Leader Chuck Schumer, a prominent Jewish Democrat, said it was an antisemitic attack.

鈥淭his is horrifying, and this cannot continue. We must stand up to antisemitism,鈥 he said on X.

The attack follows last month鈥檚 arrest of a Chicago-born man in the fatal shooting of two Israeli embassy employees in Washington, DC. Someone opened fire on a group of people leaving an event hosted by the American Jewish Committee, an advocacy group that fights antisemitism and supports Israel.

The shooting fueled polarization in the United States over the war in Gaza between supporters of Israel and pro-Palestinian demonstrators.

Colorado Governor Jared Polis posted on social media that it was 鈥渦nfathomable that the Jewish community is facing another terror attack here in Boulder.鈥 鈥 Reuters
