I rushed to Rabaa Adaweya square shortly after midnight on July 27th after hearing that security forces were attacking Morsi supporters who had been camped there for two months. Throughout the night I would alternate between the front-line, the makeshift hospital and a room where dead were kept, documenting a level of brute violence and horror I hadn't witnessed until that night. There was a constant stream of ambulances and motorbikes in the camp. The sound of sirens and panicked shouts mixed with that of live ammunition, and the air was filled with tear gas and black smoke.

Twelve hours later, I put the camera away as I got exhausted and headed back home. On my way out I heard screams and noticed a large group of people. Two men carried a dead young man who had very recently been shot in the head. The man (on the right) was in a state of shock. Unaware that the man he carried was dead, he pleaded for a medic or an ambulance and screamed for God's mercy. I quickly got the camera out and took this photo. It was the last picture I took on that horrific day, but it remains the most memorable.
