The smugglers have jumped ship again. A merchant vessel filled with migrants has been left floating — unmanned — in the Mediterranean Sea. The Ezadeen, with 400 migrants aboard, lost power in stormy seas off the Italian coast just days after another uncrewed vessel carrying 1,000 migrants was saved. Rescuers fear this is the start of a dangerous and costly new trend in human trafficking. The Italian coast guard is using helicopters to access the 197-foot ship floating off of Italy’s heel.
