Demonstrators with Run for Their Lives have staged global events since 2023 calling for Hamas to release Israeli hostages, but organizers say Sunday's walk in Boulder, Colorado, where 12 people were injured in a fiery attack, was the first in which they have faced violence. The group was wrapping their weekly demonstration at a bustling pedestrian mall when a man with a makeshift flamethrower yelled “Free Palestine” and threw Molotov cocktails into the crowd, authorities said.
