Cave divers' dangerous search of Costa Concordia wreck
Divers from the Italian Alpine and Cave Corps had been helping search for survivors inside the Costa Concordia, until the rescue operation was suspended.
The search operation was put on hold after the ship slipped further into the sea.
Diver Gian Luca Ricciardulli told the BBC's Alan Johnston that conditions for the divers were dangerous when they carried out a search on Tuesday.
He said furniture was floating and walls had become floors due to the lean of the boat.
