FBI officials have classified a violent incident in Boulder, Colorado, targeting participants walking in support of Israeli hostages held in Gaza as a terror attack.

Molotov cocktails were used in the assault, leaving several people injured. Some victims sustained life-threatening injuries and were rushed to area hospitals.

“Our agents and local law enforcement are on the scene already, and we will share updates as more information becomes available,” FBI Director Kash Patel said after the incident, confirming federal involvement in the case.

While authorities continue examining the scene, they have cordoned off several blocks surrounding the attack site, a standard protocol for incidents classified as domestic terrorism, as outlined in federal response guidelines.

The investigation remains active with evidence collection ongoing. Police have arrested Mohamed Sabry Soliman, an Egyptian national who is in the country illegally.

Federal agencies have intensified coordination with local authorities following similar incidents nationwide. Colorado Democratic Governor Jared Polis expressed concern about the situation, saying that he is “closely monitoring the situation in Boulder, and my thoughts go out to the people who have been injured and impacted by this heinous act of terror.”

Police have urged residents to avoid the area while first responders continue their work. The collaborative effort between federal and local agencies continues, and further details will likely emerge in the coming days.
