Australian mining giant BHP on Wednesday denied responsibility for a 2015 dam collapse in Brazil, one of the country's worst environmental disasters, as it opened its defence at the High Court in London.
The months-long trial will determine whether BHP is liable for the rupture at the Fundao tailing dam in Brazil that killed 19 people and unleashed a deluge of thick toxic mud into villages, fields, rainforest, rivers and the ocean.
