The Egyptians who 'disappear'
Italian PhD student Giulio Regeni went missing in Cairo on 25 January. Just over a week later, his body was found dumped with signs of torture. Regeni's family have accused the Egyptian security forces of being behind their son's murder, an accusation the Egyptian authorities strongly deny.
But human rights groups claim this was far from an isolated case. The Egyptian Commission for Rights and Freedoms says it documented 544 cases of enforced disappearance between August 2015 - April 2016 - though Egyptian authorities maintain they are being "smeared".
Nour Khalil, a human rights activist, says it happened to him and his family.
