Mining giant Vale failed to report problems at a massive tailings dam in Brazil that could have averted its collapse, killing hundreds, a government agency said on Tuesday.
Brazilian federal police have proposed criminal charges against mining giant Vale and German safety firm Tüv Süd and 13 of their employees over January's deadly dam collapse, reports say.
A report commissioned by Brazilian miner Vale SA last year to look into the stability of the tailings dam that ruptured January 25, killing 135, certified it as sound but raised concerns over its drainage and monitoring systems, newspaper Folha de S Paulo reported on Tuesday.
