Hundreds of bodies could have been buried at a mass grave discovered in Egypt’s Sinai province by human rights campaigners. The group discovered the mass graves while conducting research into disappearances and extrajudicial killings of civilians during a decade of conflict in the Sinai region between Egyptian security forces and Islamic State-aligned militants. SFHR said two members of pro-military militias had given basic information about the mass graves sites but their own researchers had then had to search for the sites themselves. Forensic Architecture confirmed that the site was probably used as a mass grave by identifying the clearing of the land and the emergence of track marks over a period of time. SFHR’s first informant told them that the bodies buried in the mass graves belonged both to people killed shortly after detention and those who had been detained for several years.
