Stop migrants becoming slaves in Libya! Close the slave markets!

Stop migrants becoming slaves in Libya! Close the slave markets!
Why this petition matters

Currently, in Libya, migrants are being sold on "slave markets".
Thousands of West African men, women and children passing through Libya are sold on "slave markets" before being subjected to forced labor or sexual exploitation (rape, forced prostitution). These people are sold for between $200 and $500 as property.
Originally from Nigeria, Senegal or Gambia, the migrants are captured as they travel to northern Libya, from where they intend to reach Europe by crossing the Mediterranean. Throughout this journey, they fall prey to armed groups and networks of smugglers who sometimes try to extort money from them.
This crime, this human trafficking must STOP immediately!
Please sign this petition to ask the Foreign Secretary, Boris Johnson, the UN and the African Union to take immediate and concrete measures to stop this human trafficking.
