The BBC's Matthew Price has been on board the Bergamini, part of the Italian navy's Mare Nostrum (Our Sea) operation, which patrols the seas in the search for migrant boats.

The frigate is under orders to save lives - whether boats are in trouble or not, they will try to intercept them and pick up the passengers.

This video, filmed on a phone, shows what happened when the vessel located a migrant boat with 270 people on board and follows the operation as it returns to Italy.
