More than 200 migrants rescued by Open Arms, a Spanish NGO, were transferred from a charity vessel to another boat for mandatory quarantine on Saturday (November 14).
The 253 migrants, including women and children, were moved to a ferry off the Sicilian port of Trapani.
They were rescued by Open Arms after their dinghy began to sink off the coast of Libya on Wednesday (November 11).
At least six people lost their lives in the shipwreck, including a 6-month-old child.
Italy is the primary route for migrants departing mostly from Tunisia and Libya to reach Europe.
Some 30,800 people have arrived so far in 2020, with numbers picking up again after years of decline marked by an Italian-led effort to disrupt smuggling networks.
