The migrants are citizens from the Maghreb states and from sub-Saharan Africa, it said, adding that most of them are doing well under the circumstances.
Units from the Spanish sea rescue service and the police took part in the rescue and recovery operations, reported the digital newspaper Crónica Balear and other regional media with reference to the responsible authorities.
