On 14 August 2013, Egyptian security forces raided two camps of protesters in Cairo: one at al-Nahda Square and a larger one at Rabaa al-Adawiya Mosque. The two sites had been occupied by supporters of ousted President Mohamed Morsi, who was removed from office by the military after mass street protests against him. The camps were raided after initiatives to end the six week sit-ins failed and as a result of the raids the camps were cleared out within hours. The raids were described by Human Rights Watch as the most serious incident of mass unlawful killings in modern Egyptian history.
