Some of the 340 illegal migrants who were rescued by the Libyan navy off the coast of the western town of Sabratha when their boat began to take on water, sit at a shelter on May 12, 2014 in the coastal town of Zawiya, west of Tripoli. The rescue came on the same day Italy's navy said at least 14 migrants had died when their boat sank between Libya and Italy, the latest in a string of shipwreck tragedies to hit the Mediterranean. Libya has long been a springboard for Africans seeking a better life in Europe, and the number of illegal departures from its shores is rising.
