A new wave of boats is attempting to cross from Libya to Italy, the International Organization for Migration warned Sunday, citing balmy weather and tranquil seas as the reasons behind the surge of migrants risking their lives in the Mediterranean.

Nearly 3,500 migrants were rescued on Saturday alone, with 1,000 more (including at least 10 pregnant women) on board relief vessels by mid-afternoon Sunday, CNN reports.

A team of ships from several European nations cooperated on a rescue effort, including the British, Irish, Spanish, and German navies and the Italian coast guard, which alone received 14 distress calls Sunday, many from wooden fishing boats and rubber dinghies. One of the biggest rescued vessels held 563 migrants.

Rescue ships planned to bring the migrants to various ports in Italy, including Palermo and Trapani in Sicily, Taranto in Italy, and the island of Lampedusa, a spokesman for Germany’s Bundeswehr Joint Forces Operation Command told CNN.

As of the end of May, the United Nations estimated that 90,000 migrants crossed the Mediterranean to Europe so far in 2015; of those, more than 1800 have died or are missing at sea.
