crowd of people gathered in a city square or plaza, waving blue and yellow flags that appear to be Ukrainian flags. The crowd is dense, and the video is shot from within the crowd, giving a sense of being surrounded by people. The building behind the crowd bears the inscription "LIGA DE EMPLEADOS DE COMERCIO BANCA E INDUSTRIA" (League of Commerce, Banking, and Industry Employees). The decorations, flags, and the presence of a stage suggest a celebration or rally. The sky is overcast. Overall, the video appears to document a public event related to Ukraine.
