Engineers held in Brazil dam collapse

Five engineers, including two working for a German company, were arrested in Brazil in a probe into a dam collapse last week at a mine in the southeast that killed 65 and left 279 missing, officials said.

Three of the engineers work for Vale, the owner of the mine, the prosecutors’ office in the state of Minas Gerais said. The other two work for a German company that carried out the last safety inspection at the mine.

Extreme events such as droughts are increasing.
