ISIS has been looting and selling ancient works of art on eBay, Whatsapp and Facebook.

Earlier this year, a video surfaced of members of the militant group destroying and looting the Mosul Museum in Iraq. Now, ISIS has set up its own government branch, known as the archeological administration in Manbij, Syria, which manages looting sites and disperses works to potential dealers.

There is an estimated $300 million dollars worth of valuables circulating through Lebanon, Turkey, and Jordan. Since the expansion of the Islamic State's reach in 2012-2013, imports from Iraq increased by 672 percent, and Syrian artifacts by 133 percent, according to the U.S. International Trade Commission.

Auction houses such as Christie's and Sotheby's have been notified to avoid any artifact originating from Syria or Iraq, as many dealers wait years before reselling the pieces in order to obtain increased value. But some experts believe the only way to stop the circulation is to secure the borders physically.
