Libya has become the main point of departure for migrants and refugees trying to cross the Mediterranean by boat to Europe since the route between Turkey and Greece was largely closed off last year. A record 181,000 made the journey last year, most on flimsy boats operated by people-smugglers. The death toll in the Mediterranean – the most dangerous border crossing on the planet for migrants and refugees – is estimated to be at least 5,000 last year.

Award-winning photojournalist David Ramos joined the crew of the Spanish NGO Proactiva Open Arms vessel Golfo Azzurro during a search and rescue mission off the coast of Libya for migrants who continue to make the perilous journey across the Mediterranean in hope of reaching the European mainland.
