At least three people have died and up to six are missing after a ship crashed into a control tower in the Italian port of Genoa, reports say.
Part of the tower is said to have crashed into the water when it was hit by the Jolly Nero container ship.
Four people were taken to hospital, but others are feared to be in the water or trapped inside the tower.
The crash triggered a frantic night-time search operation in the waters around the tower.
The cause of the crash - whether human error or mechanical fault - has not yet been confirmed.
The ship's owner, Stefano Messina, who arrived at the port soon after the crash, had tears in his eyes as he told journalists: "We are all utterly shocked. Nothing like this has ever happened before, we are desperate."
One of the victims was thought to be a woman in her 30s, while the other two were male.
