The Federal Bureau of Investigation (FBI) is investigating what authorities are calling a “targeted terror attack” that took place Sunday near Pearl Street Mall in Boulder, Colorado. According to reports, several people were injured after a suspect hurled Molotov cocktails at participants in a pro-Israel "Run for Their Lives” event. Some reports say multiple people were set on fire.
The Run for Their Lives campaign organizes global walks and runs demanding the release of Israeli hostages held by Hamas.
White House officials said that President Donald Trump has been briefed on the "targeted terror attack."
“We are aware of and fully investigating a targeted terror attack in Boulder, Colorado," FBI Director Kash Patel wrote on X. "Our agents and local law enforcement are on the scene already, and we will share updates as more information becomes available.”
