Are these women in Libya
Probably not in Libya.
are they for sale in a market, and are they for sale as slaves?
The oldest version (June 26, 2018) I can find with reverse image search yields an ivory coast paper that claims women are sold by a network of Ivorians trafficked by women based in Abidjan and sold by Kuwaitis to Kuwaiti families with no mention of Libya.
I've found the claimed location attributed to Kuwait in some twitter posts but with no sourcing.
It seems to have taken off in the last week after turning up on some right wing sites with the Libya attribution.
I can't find it on any news website other than rumeursdabidjan, just twitter, facebook and blogs.
