Who is to blame for a devastating oil spill near Brazil?

Authorities in Brazil say an oil spill off the northeast coast is one of the biggest environmental disasters ever to hit the country.

Oil has been washing up for months now with nearly 300 beaches hit, but President Jair Bolsonaro has warned that the worst is ‘yet to come’.

Brazil blames a Greek freighter for the disaster, but the ship’s owners deny any involvement.
