CAIRO: Nobel Laureate Mohamed ElBaradei held Egyptian President Mohamed Morsi responsible on Wednesday for protecting peaceful demonstrators by the presidential palace “if he wishes to retain what is left of his legitimacy". “Vicious attack vs peaceful protesters in front of presidential palace without police protection. Regime leading Egypt into violence and bloodshed." The former director of the International Atomic Energy Agency posted on Twitter on Wednesday. This comes at a time where opponents and supporters of Morsi have started scuffling by the palace. Tens of opposition protesters had set up tents by Egypt's presidential palace on Tuesday in a sit-in against a constitutional decree issued by Morsi and a draft constitution written by an Islamist-dominated assembly. Meanwhile, the Muslim Brotherhood called for a demonstration by Egypt's presidential palace earlier on Wednesday to “defend legitimacy”.
