How 'slave' migrants are used by the Greek police to pushback other migrants

Exclusive interviews lift the veil on a system of forced labor at the Greek-Turkish border, where migrants are forced by Greek border guards to illegally push back other migrants.
Over the past few months, Le Monde and its partners from Lighthouse Reports - Der Spiegel, ARD's Report München and The Guardian, with the help of the Facebook page "Consolidated Rescue Group" - interviewed six migrants who told of being "slaves" to the Greek police, forced to push other migrants away. Secret, violent and illegal operations. In exchange for doing the dirty work of Greek migration policy, they were promised a one-month residence permit that would allow them to organize their journey to Northern Europe.
