large crowd of people gathered in an urban area

large crowd of people gathered in an urban area. Many of the individuals are wearing hard hats and military-style helmets. The presence of individuals in construction gear and military attire suggests a possible inspection or security operation. Several people can be seen standing on the roof of a building that has multiple floors, as well as on balconies. There are buildings on both sides of the crowd, banners, and a large truck behind the crowd. Some members of the crowd are holding cameras and taking photos.
