Hundreds of refugees from Eritrea, Ethiopia and Somalia are feared to have died after their boat capsized in the Mediterranean en route to Italy on Monday. Survivors say that up to 500 people may have drowned, although the reports are still unconfirmed. The number of people trying to cross from Libya to Italy has surged after a controversial new deal took effect in March that calls for all refugees arriving in Greece to be deported to Turkey. Monday’s disaster comes nearly one year after a refugee boat capsized in the Mediterranean on April 19, 2015, killing as many as 800 people. After Monday’s news broke, Doctors Without Borders tweeted: “2016, the Mediterranean is a mass grave.”
