500 small pigs were trapped in their pens after parts of a roof at a pig farm near Brålanda in western Sweden collapsed on Saturday.
A thousand pigs were evacuated. Half of the 1,500 square metre ceiling collapsed. Rescue attempts were hindered by concerns over netering the building with parts of the roof still standing.
A number of roofs have collapsed in Sweden in the past week, particularly in the west, because of the unusual amount of heavy snow.
