ROME: Dozens of migrants were dramatically rescued by Italy as they foundered in the sea or clung to a rocky reef on Sunday after three boats launched by smugglers from northern Africa shipwrecked in rough waters in separate incidents over the weekend. Survivors said some 30 fellow migrants were missing from capsized vessels. In a particularly risky operation, two helicopters battled strong winds to pluck to safety, one by one, migrants stranded for nearly two days on a steep, rocky reef of tiny Lampedusa island. Firefighters said all the migrants, including a child, who had been clinging to the rocks after their boat smashed into the reef late Friday early Saturday.
