“Eight hundred,” says the auctioneer. “900 … 1,000 … 1,100 …” Sold. For 1,200 Libyan dinars — the equivalent of $800.

Not a used car, a piece of land, or an item of furniture. Not “merchandise” at all, but two human beings.

One of the unidentified men being sold in the grainy cell phone video obtained by CNN is Nigerian. He appears to be in his twenties and is wearing a pale shirt and sweatpants.

He has been offered up for sale as one of a group of “big strong boys for farm work,” according to the auctioneer, who remains off camera. Only his hand — resting proprietorially on the man’s shoulder — is visible in the brief clip.

After seeing footage of this slave auction, CNN worked to verify its authenticity and traveled to Libya to investigate further.
