Russian rescue workers ended a search for survivors a day after a roof collapsed at a water park, killing at least 25 people and injuring more than 100. 17 people remain missing, presumably buried under debris of the Transvaal Park on Moscow's south-western outskirts. Rescuers shovelled snow from the tangled mass of steel and concrete, some standing atop a large stone that appeared to be part of a mock tropical scene. They also brought in generators and search dogs, which cut their paws on broken glass while sniffing through debris.
