Brazil's dead penguin mystery
Environmental police are investigating the deaths of at least 180 oil-soaked penguins which have been washed ashore in southern Brazil in the past week.
The police believe the incident was caused by a major fuel spill near the coast of Santa Catarina state.
Another 200 Magellanic penguins which washed up in the same area are being treated in an animal protection and recovery centre.
