The deaths of at least 13 people early Monday on an overloaded migrant boat that capsized near the Italian island of Lampedusa have galvanized calls to shut down smuggler routes and revamp search-and-rescue efforts in the deadly central Mediterranean Sea. The Italian coast guard said one of its vessels was about to begin the rescue about six nautical miles Italy’s southernmost island when the boat capsized. The incident brings to more than 1,000 the number of people who have died in the Mediterranean Sea this year.
