Gulf spill worse than BP estimates

A US judge has said more oil spilled into the Gulf of Mexico following the deadly rig explosion in 2010 than BP estimated – a decision that could potentially cost the oil giant $13 billion.

District judge Carl Barbier ruled in New Orleans that 3.19 million barrels were discharged into the Gulf after the rig explosion at BP’s Macondo well, one of America’s worst environmental disasters, that killed 11 workers.
