Interim Vice-President Mohamed ElBaradei has called for an end to the "polarisation" in Egypt following Mohamed Morsi's removal from power.
"It is time that we end this miserable state of polarisation using rational means. We have to be tolerant so that [Egyptian men and women] can build Egypt," ElBaradei said via Twitter.
Earlier on Friday, the former leading member of Egypt’s National Salvation Front (NSF) said that "non-violence, rule of law… and reconciliation based on inclusiveness are key principles to adhere to during this difficult time."
On Friday, millions took to the streets in Cairo to heed calls by Egypt's army chief Abdel Fattah El-Sisi to give the army and the police a "mandate" to combat "violence and terrorism."
Since the popularly-backed removal of the former president on 3 July, clashes between supporters and opponents of the deposed president have left more than100 dead on both sides.
On Thursday, the army gave the Muslim Brotherhood until Saturday to sign up to national reconciliation as a way out of the current political strife.
Thousands of supporters of ousted president Mohamed Morsi, led by the Muslim Brotherhood, also took to the streets to call for the president’s reinstatement. They also have maintained a sizeable vigil outside the Rabaa Al-Adawiya Mosque in Cairo's populous Nasr City district for close to a month in protest.
