The wall, which divides the street in half, is part of increased security around the palace - which has been manned by the Republican Guard since Thursday - ahead of expected protests. 13:00 Good afternoon, we open our live coverage of nationwide protests against President Mohamed Morsi's decision to stick by his decree and the constitutional referendum. Thousands are expected to converge on the Heliopolis presidential place from 17 venues across Cairo, Friday, in protest of President Mohamed Morsi's decision to stick by his controversial Constitutional Declaration and the upcoming constitutional referendum, as announced during his televised statement Thursday. In the long awaited speech, Morsi blamed “infiltrators” and “third parties” for causing the bloody clashes between Brotherhood supporters and protesters on Wednesday night at the presidential palace, which saw seven dead. He also accused opposition forces of “serving the interests of the remnants of the former regime” to overthrow his legitimate rule. The president refused to bow to the demands of opposition coalition the National Salvation Front, who demand he rescind the Constitutional Declaration and re-form the Constituent Assembly, saying that his recent decisions were necessary. However, Morsi called for Saturday talks with his opponents. This was promptly rejected by the National Salvation Front who said that following the recent bloodshed they could not open dialogue with the president while he “ignores the demands of the people.” There have been violent scenes across the country since Morsi issued his contentious decree, as rival protest groups meet and clash. Muslim Brotherhood and Freedom and Justice Party offices nationwide have also been attacked: Thursday night saw the Brotherhood headquarters in Moqattam torched by angry demonstrators.
