Dangerous task for divers in ship's rescue operation

The owners of the luxury cruise ship wrecked off the Italian coast are blaming their own captain for the disaster.
They say he went off course without authorisation. The captain blames the disaster on rocks which were not on his chart.
At one point on Monday the rescue operation to find those still missing was postponed when the Costa Concordia slipped further into the sea.
