Supporters of ousted president Mohammed Morsi were planning fresh protests across Cairo on Sunday, raising fears of further bloodshed after hundreds were killed this week, dpa reported.
In defiance of the military-backed government's crackdown, Morsi's Muslim Brotherhood group and its Islamist allies announced they will hold at least nine marches across the Egyptian capital, and gather neat the Constitutional Court in southern Cairo.
The rallies come as the government mulls legally dissolving the Brotherhood and prosecutors question 250 supporters of Morsi on murder and terrorism charges.
The government accuses Islamist leaders of inciting violence and has vowed to deal firmly with what it called "powers of terrorism and sabotage."
Violence began on Wednesday when security forces launched crackdowns on two major pro-Morsi demonstrations in Cairo. About 750 people were killed during the crackdown and the ensuing violence across the country.
The stock market and banks will re-open on Sunday, after being closed since Wednesday, when Egypt imposed a state of emergency and a curfew in around 12 provinces.
The army's overthrow of Morsi July 3, after protests by millions of Egyptians demanding he step down, has deeply divided Egypt, which is the Arab world's most populous country.
The clampdown on Islamist protesters has drawn international condemnation, mainly from Europe and the United States. However, the Gulf countries have expressed support for Egypt's interim rulers.
UN Secretary General Ban Ki-moon said Saturday that he was alarmed by the violent protests and excessive use of force in response.
"He urges those in the street and those in authority to use maximum restraint and shift immediately to de-escalation," he said.
