Niger serves as a transit point for West Africans hoping to reach Europe to start a better life.
Every year, tens of thousands of migrants cross the Sahara to reach Libya. From the Libyan coast they board rickety boats to ferry them to Europe.
Many drown in the Mediterranean but, perhaps, less well known, are the dangers they face while crossing the Sahara.
It’s not known how many deaths there are every year – as it’s a vast, ungoverned region. But many migrants die of thirst, while others are robbed and attacked by criminal gangs and security forces.
