TUNIS (Reuters) – About 40 Tunisian migrants were missing after setting off in a boat toward the Italy coast last week, the national guard said on Tuesday. Tunisia is facing a migration crisis and has replaced Libya as a main departure point for people fleeing poverty and conflict in Africa and the Middle East in the hope of a better life in Europe. National Guard video footage showed coast guard ships supported by aircraft searching for the missing people. (Reporting by Tarek Amara; Editing by Chris Reese)
