Satellite images show excavation at suspected Syria mass grave site

Satellite images reveal excavation at the site of a suspected mass grave outside of the Syrian capital taken throughout several years. The head of a U.S.-based Syrian advocacy organization, Mouaz Moustafa, said on Monday (December 17) that a mass grave outside of Damascus contained the bodies of at least 100,000 people killed by the former government of ousted President Bashar al-Assad.
