TOPSHOTS Residents walk through debris and rubble inside the burnt down mosque of Rabaa al-Adawiya on August 15, 2013 in Cairo, Egypt. Islamists vowed to rally later in the day in support of deposed president Mohamed Morsi despite a violent crackdown that sparked Egypt's worst day of violence for decades, with over 500 people killed. As the death toll from the carnage soared, condemnation of the previous day's crackdown on two Muslim Brotherhood protest camps in Cairo poured in, with Britain, France and Germany summoning the country's ambassadors to express concern.
