Hopes faded of finding survivors of the latest Mediterranean boat tragedy, in which an estimated 200 migrants drowned on Thursday as rescue ships were called to the aid of more migrant boats in the same area, Reuters reported Vessels from the Italian and Irish navies and humanitarian agency Medecins sans Frontiers (MSF) saved more than 370 people from a capsized boat thought to be carrying up to 600 on Wednesday, the Italian coast guard said. They recovered 25 bodies but found no more survivors after scouring the waters overnight. Italian vessels continued to search the area on Thursday, a coastguard spokesman said. Initial reports put about 700 passengers on the overcrowded fishing boat but interviews with survivors - mostly Syrians fleeing their country's civil war - reduced that estimate and the figure could still change.
