Video captures 130-foot superyacht sinking off southern coast of Italy

Footage has emerged of the moment a superyacht completely sank into the Mediterranean Sea.

The 40-metre vessel got into difficulty about 15km off the Catanzaro Marina in Italy.

The Italian coastguard rescued all nine people on board - four passengers and five crew - which was heading from Gallipoli to Milazzo when it sank.

The reason the yacht sank is being investigated.
