ROME (Reuters) - More than 80 migrants were saved, but two died and three were missing following two sea rescue operations in the Mediterranean off the coast of Libya, the Doctors Without Borders (MSF) charity said on Sunday. MSF's vessel Geo Barents picked up over 60 people late on Saturday from a rubber dinghy in distress in international waters off Libya. It also recovered one body, and one of the migrants taken on board died shortly after the rescue. Mediterranean sea crossings from North Africa to Italy or Malta are among the world's most dangerous migration routes. Last year almost 2,500 migrants died or went missing on those routes, according to the International Organization for Migration.
