ROME (AP) — Italian authorities are scrambling to relieve overcrowding in shelters after scores of boats carrying migrants reached Italy’s southern shores and tiny islands over the weekend. Italian media said that nearly 50 boats arrived between Friday night and Saturday. Some of the vessels launched by migrant smugglers held as few as eight passengers. Many of them were from Tunisia. Other boats reached the shores of the Italian mainland. The Italian news agency ANSA said Sunday that 92 migrants reached Puglia in a sailboat.
