Pro-ISIS Hackers Delete Syrian Humanitarian Files

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.

The hackers allegedly also displayed messages in English and Arabic that used threatening and derogatory language toward the Observatory.

The attack prompted the organization to take down its site.

The Observatory has said it has been "documenting the human rights situation in Syria and reporting all human rights violations" on all sides of the conflict.

Abdelrahman said the incident will not scare the organization away from its work.
