The eight operations took place between 30 and 40 nautical miles off the Libyan coast, including the rescue by Doctors Without Borders ship Bourbon Argos of over 776 people.
Italy's coastguard vessel Dattilo picked up 1,137 migrants from two boats, while its Corsi vessel rescued 137 people from a deflating dinghy on which the body of a woman was also recovered.
A further 231 people were rescued from two other dinghies which had run into difficulty in the perilous crossing from Libya to the Italian shores.
