An investigation into the 2010 accident in Chile that left 33 miners trapped underground for more than two months has failed to find anyone responsible.
The case was closed after a prosecutor said there was not enough evidence to press charges against either the owners of the mine or regulators.
One of the miners said it was a "disgrace for justice" while a former minister called it "unbelievable".
The miners' rescue in a special capsule was followed live around the world.
