Italy is moving to stem the flow of migrants from North Africa. Since 2014, Italy has received 500,000 migrants and refugees who have fled war, extreme poverty and oppressive regimes in their home countries. They've mainly crossed the Mediterranean Sea from North Africa, a route that has killed at least 12,000 people who have attempted the treacherous journey. But while Italy has had a reputation of welcoming migrants, that sentiment is beginning to change. On Saturday, NewsHour Weekend Special Correspondent Nadja Drost reports on how Italy is now discouraging and containing the migrant flow and how the European Union is helping to influence their fate.
