Survivors of the Costa Concordia shipwreck and relatives of the 32 people who died marked the first anniversary of the grounding with the unveiling of memorials to the victims.

A Mass and a minute's silence marked the exact moment that the cruise ship rammed into a reef off Tuscany.

Relatives of the dead threw flowers into the sea and embraced as they watched the ceremony from a specially-chartered ferry.

The ship's captain, Francesco Schettino, is accused of multiple manslaughter, causing a shipwreck and leaving the ship before all passengers were evacuated.

He has not been charged but is living under court-ordered restrictions pending a decision on whether to indict him.
