Colorado Terror Attack: Unpacking the Boulder Flamethrower Incident and Its Broader Implications

Introduction: A Shocking Act of Violence in Boulder

On June 1, 2025, a peaceful gathering at Boulder’s Pearl Street Mall turned into a scene of chaos when a man wielding a makeshift flamethrower attacked a group advocating for Israeli hostages in Gaza. The suspect, identified as 45-year-old Mohamed Sabry Soliman, allegedly shouted “Free Palestine” while hurling Molotov cocktails and using an incendiary device, injuring eight people, some with severe burns. The FBI is investigating this as a “targeted terror attack” and a federal hate crime, raising questions about rising ideological violence in the U.S. This blog post dives into the details of the incident, its context, and what it means for the nation’s ongoing struggle with politically motivated violence.

What Happened in Boulder?

The attack occurred during a weekly event organized by the volunteer group “Run For Their Lives,” which gathers to raise awareness for Israeli hostages held in Gaza amid the ongoing Israel-Hamas conflict. Around 2 p.m. on Sunday, Soliman, described as a shirtless man wielding a makeshift flamethrower, approached the group at the popular pedestrian mall in Boulder, Colorado, about 30 miles from Denver. Witnesses reported hearing him yell “Free Palestine” and “End Zionists!” as he threw incendiary devices, including Molotov cocktails, into the crowd. Eight victims, aged 52 to 88, were hospitalized, with injuries ranging from minor to severe burns.

The FBI swiftly labeled the incident a “targeted act of terrorism.” Soliman, an Egyptian national reportedly in the U.S. illegally after overstaying his visa, was arrested and booked into Boulder County Jail. According to the FBI, Soliman admitted to planning the attack for a year, specifically targeting what he called a “Zionist group.” The incident coincided with the Jewish holiday of Shavuot, adding a layer of sensitivity to an already charged situation.

Context: A Surge in Ideologically Motivated Violence

This attack comes amid heightened tensions in the U.S. over the Israel-Palestine conflict. Just over a week earlier, on May 22, 2025, a man shouting “Free Palestine” fatally shot two Israeli embassy staffers outside a Jewish museum in Washington, D.C. The Boulder incident follows a pattern of rising antisemitic and ideologically driven attacks, with the Anti-Defamation League noting a spike in such incidents since the Hamas attack on Israel on October 7, 2023, which sparked the ongoing war in Gaza.

The FBI, under Director Kash Patel, has emphasized that the Boulder attack is being investigated as an act of terrorism driven by ideological motives. Colorado Attorney General Phil Weiser called it a likely hate crime, given the targeting of a pro-Israel group. The Justice Department has also condemned the attack as a “needless act of violence,” pointing to a broader trend of violence driven by racial, religious, or ethnic motivations.

Who is Mohamed Sabry Soliman?

Details about the suspect remain limited, but authorities have confirmed that Soliman is a 45-year-old Egyptian national who entered the U.S. two years ago and overstayed his visa. Some sources, including journalist Laura Loomer, have claimed he is originally from Kuwait, though the FBI has not corroborated this. The Trump administration has labeled him an “illegal alien,” sparking debates about immigration policies and their intersection with national security. Soliman’s alleged year-long planning suggests a premeditated act, raising questions about how such intentions went undetected.

Community and Official Responses

The attack has drawn widespread condemnation. Colorado Governor Jared Polis called hate-filled acts “unacceptable” and said he is closely monitoring the situation. U.S. Representative Joe Neguse expressed prayers for the victims and is in contact with local law enforcement. The Anti-Defamation League highlighted the attack’s occurrence during the “Boulder Run for Their Lives” event, underscoring the targeting of a Jewish community gathering.

However, the incident has also sparked polarized reactions. Some conservative voices, including supporters of Israel, have labeled pro-Palestinian activism as inherently antisemitic, pointing to this attack as evidence. Meanwhile, others, like a witness named Segal, who is Jewish and supports Palestine, expressed concern about being unfairly associated with the attacker due to her pro-Palestine stance. This reflects the broader challenge of navigating free speech, activism, and violence in a deeply divided political climate.

The Broader Implications

The Boulder attack highlights several critical issues:

1. Rising Antisemitism: The incident is part of a troubling increase in antisemitic violence in the U.S., with the FBI noting a surge in such incidents. This attack, occurring during a Jewish holiday, underscores the vulnerability of Jewish communities amid global tensions.

2. Ideological Extremism: The FBI’s classification of the attack as terrorism points to the growing threat of ideologically motivated violence. Whether driven by religious, political, or ethnic motives, such acts challenge law enforcement’s ability to prevent lone-wolf attacks.

3. Immigration and Security Debates: Soliman’s status as an undocumented immigrant has reignited discussions about border security and vetting processes. Critics of current policies argue that lax enforcement enabled this attack, while others caution against broad generalizations about immigrants.

4. Polarization and Free Speech: The attack raises questions about the line between activism and violence. While “Free Palestine” is a common slogan in pro-Palestinian protests, its use in a violent context risks further stigmatizing legitimate activism.

What’s Next?

Authorities are continuing their investigation, with the FBI and Boulder Police searching for additional evidence. Soliman faces multiple felony charges, including a federal hate crime, which could carry significant penalties. The Justice Department’s involvement suggests a thorough probe into whether Soliman acted alone or had connections to broader networks.

The attack also puts pressure on policymakers to address rising antisemitism and ideological violence. Proposals range from increased funding for community security to stricter immigration enforcement, though solutions remain contentious. Meanwhile, communities in Boulder and beyond are left grappling with fear and division.

Conclusion: A Call for Reflection

The Boulder flamethrower attack is a stark reminder of how global conflicts can spill into local communities, fueling violence and division. As the U.S. navigates a polarized political landscape, incidents like this demand a careful balance between security, free speech, and community healing. The FBI’s swift response and the outpouring of support for the victims are steps toward justice, but broader questions remain about how to prevent such tragedies in the future.

Thought Questions for Readers:

1. How can communities balance free speech and activism with the need to prevent ideologically motivated violence?

2. What role should immigration policies play in addressing national security concerns without stigmatizing entire groups?

3. How can the U.S. address the rise in antisemitic incidents while fostering dialogue on contentious global issues like the Israel-Palestine conflict?
