The FBI says it is investigating a “targeted terror attack” in Colorado after a man reportedly threw petrol bombs at a pro-Israel event.

FBI boss Kash Patel said agents were working with local law enforcement on the scene in Boulder.

Witnesses told US media the attacker threw Molotov cocktails at people doing a walk to remember Israeli hostages in Gaza.

A male suspect is in custody.

Local police said there were “multiple victims” and a large part of the downtown area around Pearl Street was cordoned off.

Police chief Steve Redfearn said it happened around 1.26pm local time and initial reports were that “people were being set on fire”.

He said some victims were in hospital and injuries ranged from “very serious” to “more minor”.

“When we arrived we encountered multiple victims that were injured, with injuries consistent with burns,” Mr Redfearn told the media.

He said a suspect had been pointed out and taken into custody without incident.

“This area is not safe yet and we’re dealing with a vehicle of interest,” he added.

Mr Redfearn said it happened as a “group of pro-Israel people” were peacefully demonstrating, but that he couldn’t confirm a specific group had been targeted.

The police chief said it was too early to call it a “terror attack”. However, Colorado’s governor did use those words.

Jared Polis said on Facebook it was “unfathomable that the Jewish community is facing another terror attack here”.

A joint statement from Boulder’s Jewish community said “an incendiary device was thrown at walkers at the Run for Their Lives walk on Pearl Street as they were raising awareness for the hostages still held in Gaza”.

It added: “Our hearts go out to those who witnessed this horrible attack, and prayers for a speedy recovery to those who were injured.”

Colorado attorney general Phil Weiser said it “appears to be a hate crime” and that “violence is never the answer to settling differences”.

His statement said the group affected gathered weekly on Pearl Street to call for the release of the remaining hostages held by Hamas.

Boulder is a university city of about 105,000 people on the northwest edge of Denver, in the foothills of the Rocky Mountains.
