Lampedusa is the destination of choice for smugglers who usually charge more than 1,000 euro (£850) a head and cram the migrants onto boats that routinely run into trouble and require rescue.
Fortress Europe, an Italian observatory that tracks migrant deaths reported by the media, says about 6,450 people died in the Canal of Sicily between 1994 and 2012.
