The ISIS group released a video on Thursday purportedly showing militants using sledgehammers to smash ancient artifacts in Iraq's northern city of Mosul, describing them as idols that must be removed.The destructions are part of a campaign by the ISIS extremists, who have destroyed a number of shrines including Muslim holy sites in order to eliminate what they view as heresy.They are also believed to have sold ancient artifacts on the black market in order to finance their bloody campaign across the region.The five-minute video shows a group of bearded men inside the Mosul Museum using hammers and drills to destroy several large statues, which are then shown in pieces and chipped.The video then shows a black-clad man at a nearby archaeological site inside Mosul drilling through and destroying a winged-bull Assyrian protective deity that dates back to the 7th century B.C.- See more at: en.alalam.ir/news/1680239#sthash.teGXTsLJ.dpuf
