During the height of the migrant crisis in 2016, over 11,000 Nigerian women made the journey to Italy in the hope of making a better life.
It’s estimated that 80% were trafficked and forced into prostitution.
Before they left home many were made to undergo a juju, or black magic, ceremony in which they swore – on pain of death – they would pay back their traffickers.
The strain of believing they were living under a spell has added to their mental health problems.
One women, Magdalen, shared her story with the BBC.
