Won't give up

A group of people in helmets and protective gear, including some in yellow vests, are inside and around a building with large glass windows, where a cloud of white smoke or powder erupts from inside. The individuals move rapidly, some running out of the building, while others inside react to the disturbance, with one person falling to the ground as debris scatters. The scene takes place at night, with the area illuminated by a red light.
