Thousands of migrants from sub-Saharan Africa wait near the coast in Tunisia for an opportunity to make the treacherous voyage across the Mediterranean. Under an agreement signed with the European Union, the Tunisian government does what it can to stop them. NGOs and migrants accuse the Tunisian coastguard of deliberately sinking migrant boats at sea, leaving those on board to drown. Others say migrants are regularly bused out to the desert and abandoned. We investigate these allegations and meet the humans caught in the crossfire of a political battle over migration.
