ISIS has buried up to 15,000 people in 72 mass graves, AP says, with more to be found

The Islamic State overran large swathes of Syria and Iraq in the summer of 2014, and the militants left traces of their massacres dotting the landscape. In a new report, The Associated Press identifies 72 mass graves in Syria and Iraq, and says many more will be uncovered as ISIS's territory shrinks. "This is a drop in an ocean of mass graves expected to be discovered in the future in Syria," says Ziad Awad, the editor of online publication The Eye of the City, who is trying to document ISIS's mass burial plots.

Using satellite imagery, photos, and interviews, AP has found the location of 17 mass graves in Syria, and 16 of the mass graves the news organization located in Iraq are in areas still to dangerous to excavate. AP says anywhere from 5,200 to more than 15,000 ISIS victims are buried in the graves it knows about. "They don't even try to hide their crimes," Sirwan Jalal, director of the Iraqi Kurdistan agency in charge of mass graves, tells AP. "They are beheading them, shooting them, running them over in cars, all kinds of killing techniques, and they don't even try to hide it."

The evidence and chance to identify the dead are waning with the passage of time and exposure to the elements, however, and the Iraqi Kurds and other local groups are seeking international help. Part of the goal is to build a case to convict ISIS leaders of war crimes, and part of it is so families can bury their dead. "We want to take them out of here," Rasho Qassim, an Iraqi Yazidi, says of the remains of his two sons. "There are only bones left. But they said 'No, they have to stay there, a committee will come and exhume them later'.... It has been two years but nobody has come."
