Clashes broke out in in Talaat Harb Street in Cairo's downtown between pro- and anti- Morsi protesters. Reportedly, Brotherhood supporters attacked the anti-Brotherhood protesters. Controversial anti-revolution television presenter Tawfiq Okasha and former MP Mohamed Abu-Hamed called for mass protests to "end Muslim Brotherhood rule" on Friday 24 August. The call was at first dismissed as an attempt by former regime loyalist, Okasha, to make a comeback into the public sphere. However, the call was soon endorsed by groups fearful of Muslim Brotherhood dominance in the country after President Mohamed Morsi, a long-time member of the group, gave himself extraordinary powers and retired Egypt's military rulers earlier this month. More details from Tahrir Square to follow shortly.
