The massacre of at least 1,150 demonstrators by Egyptian security forces in a series of protests between July and August 2013 was systematic, methodical, and premeditated, Human Rights Watch (HRW) charged in a 188-page report.More here
The killings — many of which were carried out during the dispersal of a sit-in in support of ousted president Mohamed Morsi in Cairo's Rabaa al-Adawiya Square on August 14 — "most likely" amounted to crimes against humanity, the human rights watchdog said.
Egyptian officials declined to collaborate with HRW, but rejected the report after its release. They also made clear they didn't like the accusations on Sunday when authorities at Cairo's airport stopped HRW's executive director Kenneth Roth and Middle East and North Africa director Sarah Leah Whitson, denying them entry to the country without explanation.
