"BRASILIA/RIO DE JANEIRO - A thick sludge of crude oil has been washing up on vast stretches of Brazil’s coast for nearly two months, and authorities and experts have been baffled by its origin.
This is what is known about the environmental disaster and what remains a mystery.
Oil has washed up along thousands of kilometers of beaches, mangroves and reefs on the shores of nine states in northeastern Brazil. More than 100 beaches have been affected, including some of the country’s most famous."
