crowd of people, mostly men, gathered on a street next to a mosque. The street is lined with cars and a truck. There is debris on the road, possibly broken concrete or stones, and a white substance that could be spilled liquid or powder. People are milling about, some looking at the truck, others talking amongst themselves. The scene appears to be taking place in a city or town with buildings visible in the background. The weather seems clear and sunny.
