More than 1,800 migrants have been picked up in the Mediterranean and 13 bodies recovered as the exodus from north Africa by boat endures, Italy's coast guard said on July 28. The 13 bodies were recovered by an Irish military ship after it came to the aid of one of the boats, which was carrying 522 people. AFP PHOTO / GIOVANNI ISOLINO
