Scores of Morsi supporters killed at Cairo protest

Egyptian security forces shot dead dozens of supporters of ousted Islamist President Mohamed Morsi, days after the army chief called for a popular mandate to wipe out "violence and terrorism." A video handout provided by the Muslim Brotherhood showed riot police firing weapons on top of vehicles. Another clip showed an unknown man firing a weapon and an on-screen strapline saying: "Camera operators targeted by police forces during Al-Azhar university massacre."
