It wasn't only the Muslim Brotherhood at this protest. They were people who are against the military dictatorship. A young woman told me: "I'm an Egyptian and that's all what I have in common with the Muslim Brotherhood. We are all against the military ruling our country."
People were shouting: "Why did you give Sisi authorization to kill our brother, to kill our sister?", "Sisi is a killer!", "Thepolice and the army have blood on their hands!", "Down with the military dogs!"
