Integration Minister Cecile Kyenge was on the dock of the remote outcrop as corpses were being unloaded, after calling for an easing of Italy's tough rules against illegal immigration.

Prime Minister Enrico Letta meanwhile said EU Commission president Jose Manuel Barroso will visit the island on Wednesday and blamed Libya for the growing influx of asylum seekers in Italy.
In an interview with news channel SkyTG24, Letta said Libya -- where the shipwreck boat departed from -- should adopt "stringent" measures to stop the migrant boats from leaving its shores.
Letta also called for more European assistance to cope with the influx, saying: "Italy cannot be the first country to have everything on its shoulders."
