A rescue ship has docked in Sicily with 606 migrants picked up in less than two days off the Libyan coast.
They are from about 20 countries in Africa and the Middle East. Aid group SOS Méditerranée says they include 241 children and 11 pregnant women.
Fifty had fled to Libya from war-torn Syria. But violence also plagues Libya.
The flow of irregular migrants to southern Europe via the Mediterranean is well below the 2016 level. But Italy is struggling to cope, as most migrants now take the perilous central Mediterranean route from Libya.
The Syrians taken aboard the Aquarius rescue ship include entire families and two women in the ninth month of pregnancy.
The ship is now in Palermo, where the migrants face a long screening process, to determine who among them can legitimately claim asylum.
