CAIRO, Dec. 5 (Xinhua) -- Fresh clashes raged in the Egyptian presidential palace in the region of Heliopolis between supporters and opponents of Egyptian president Mohamed Morsi, witnesses told Xinhua Wednesday.
Earlier in the day, clashes continued in central Cairo's Tahrir Square between members of popular organizations securing the square and a number of vendors.
The renewing clashes in the two scenes have left four people injured, according to a statement by Egypt's Health Ministry.
Some pro-Morsi protesters who have marched to the palace removed by force tents of anti-Morsi people, state TV reported, after Egyptian Islamists called for a demonstration supporting Morsi outside the palace.
On Tuesday evening, protesters marched from Tahrir Square and other Cairo neighborhoods to the presidential palace to protest against the beleaguered constitutional declaration and the upcoming constitutional referendum.
They called for reform of the Islamist-dominated Constituent Assembly, stopping the constitution referendum scheduled for Dec. 15, and abolishing the constitutional declaration issued last month, which they considered as Morsi's adoption of sweeping powers.
A total of 77 were injured during the clashes in Cairo and other governorates, including 40 security personnel, official MENA news agency said.
