In a Thursday statement, the Brotherhood slammed the Egyptian army, ahead of mass protest rallies planned for Sunday against the Egyptian military and its forced ouster of Morsi on July 3.

The development comes as supporters of the military-installed government are also planning a rival rally on the same day in the capital, Cairo, raising fears of violent clashes between the two sides.

The military supporters claim the want to mark the anniversary of the beginning of Egypt's 1973 war with the Israeli regime.

Egypt plunged into unrelenting violence on July 3, when the army ousted Morsi, suspended the constitution, and dissolved the parliament. It also appointed the head of the Supreme Constitutional Court, Adly Mahmoud Mansour, as the new interim president.

The army-backed interim government soon launched a deadly crackdown on Morsi supporters and arrested thousands of Muslim Brotherhood members. Among the arrested was the group's supreme leader, Mohamed Badie, who was detained on August 20.

Last month, an Egyptian court banned the Islamic group, and ordered the seizure of its funds in a heavy blow to the movement.
