“The director of the British-based Syrian Observatory for Human Rights, Rami Abdelrahman, said members of a group calling themselves ‘The Cyber Army of the Khilafah’ deleted files from the Observatory’s site, and posted a mock image of him in an orange jumpsuit kneeling beside a black-clad militant holding a knife. The picture imitates scenes from ISIS execution videos, whose victims have included journalists and aid workers.”
