Fifteen people were injured at an outdoor mall in Boulder, Colo., by a man police say attacked demonstrators with makeshift incendiary devices and a flamethrower while they were calling for the release of Israeli hostages in Gaza.

The local chapter of the organization hosts weekly runs and walking events aimed at bringing attention to the Israeli hostages taken in Hamas' Oct. 7, 2023, terror attack. In Colorado, the group has chapters in Boulder and Denver.

In the wake of the June 1 attack on a pro-Israel demonstration, community members and officials condemned the act and offered support to the community.
