Two leading figures in Egypt who backed the army’s ousting of the Islamist president Mohamed Morsi have condemned the killing of a large number of his supporters in clashes with security forces in the capital Cairo. The Grand Imam of Al-Azhar mosque has called for investigation while the vice president of the interim government Mohamed EIBaradei said that excessive force was used. The Egyptian ministry of health says at least 65 people were killed after the security forces had been ordered to end the sit-in organized by the Muslim Brotherhood at the Rabaa al-Adawia mosque. Jim Muir reports.

Tens of thousands of Morsi’s supporters and their families remain stubbornly in count in the big area around the Rabaa al-Adawia mosque in eastern Cairo. Despite what they are calling a massacre in the early hours of the mourning they are absolutely adamant that they are going nowhere until their key demand is met: the reinstatement of Mohamed Morsi as president. That’s clearly out of the question for the interim government and its military backers. They’ve indicated they intend to clear out the protesters soon peacefully if possible.

The American secretary of state John Kerry has expressed deep concern over the latest violence in Egypt. In a statement he described the situation as a pivotal moment for the country and called on the Egyptian authorities to respect the right of peaceful assembly. Katy Watson reports from Washington.
