The FBI is investigating a “targeted terror attack” after several people were injured in Colorado.

The suspect attacked people with Molotov cocktails as they took part in a walk to remember Israeli hostages still in captivity, CBS reported.

“We are aware of and fully investigating a targeted terror attack in Boulder, Colorado,” said FBI Director Kash Patel on Sunday.

Boulder Police said they were evacuating several blocks of the typically popular pedestrian Pearl Street Mall area, saying that there were “several victims” in the attack.

Steve Redfearn, Boulder Police Chief, said the suspect was taken into custody “without incident” and police were gathering evidence from a “vehicle of interest”.

“This act is unacceptable,” he said. “I ask that you join me in thinking about our victims, the families of the victims, and everyone involved. 

“Our hearts go out to them.”

Colorado Governor Jared Polis said in a statement that he was “closely monitoring” the situation, adding that “hate-filled acts of any kind are unacceptable”.

“I am 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. Hate-filled acts of any kind are unacceptable,” he wrote on X.

“While details emerge, the state works with local and federal law enforcement to support this investigation. More information will be provided as it becomes available.”

Footage posted on social media shows a shirtless man wearing sunglasses and holding two glass bottles. At one point, he is confronted by onlookers, including one who says: “He is spraying alcohol... he is making Molotov cocktails.”

Run For Their Lives, which organised the walk, said, “This is not a protest; it is a peaceful walk to show solidarity with the hostages and their families, and a plea for their release.”

The attack comes a week after two Israeli embassy staff were shot dead as they left a reception for diplomats near Washington’s Jewish museum.

Elias Rodriguez, 30, was arrested after allegedly shooting Yaron Lischinsky and Sarah Milgrim, who were soon to be engaged.

He was charged with two counts of first degree murder. He was also charged with murder of foreign officials, causing death with a firearm, and discharging a firearm in a crime of violence.
