Brazilian president Jair Bolsonaro has warned the "worst is yet to come" from an oil spill blamed on a Greek tanker.
He also reiterated prosecutors' belief that the leak of crude that has washed up on 2,100 km of north-eastern beaches came from a vessel that made a voyage matching that of one carried out by Delta Tankers' 164,000-dwt suezmax Bouboulina (built 2006), 700km out at sea in July, something the company has denied.
