Ship crews have pulled more than 2,000 refugees from overcrowded boats in the Mediterranean, Italy’s coastguard has said, as people-smugglers stepped up operations during two consecutive days of good weather.

More than 7,100 people have now been rescued from international waters since Thursday, many of them on the dangerous journey from Libya.

Europe’s worst immigration crisis since the second world war is in its third year, and there has been little sign of any let-up in the flow of people coming from North African to Italy.

Ships belonging to Doctors without Borders, Migrant Offshore Aid Station, Italy’s navy, the EU’s border agency Frontex and the bloc’s anti-people-smuggling mission Sophia all helped take the migrants off nine boats on Friday.

About 60,000 boat refugees have been brought to Italy so far this year, according to the interior ministry.
