Egypt's Freedom and Justice Party has announced that it will hold a million-man march on Wednesday after Tarawih
, night prayers during the month of Ramadan, which ends between 10pm and 11pm.
The marches, dubbed as a day of "determination" and calling for the release and reinstatement of deposed president Mohamed Morsi, will kick off from several locations in Egypt's capital.
One march will move from Rabaa Al-Adawiya Mosque in Cairo's Nasr City, where Islamists have been staging a sit-in for almost 18 days, to the nearby Republican Guard headquarters in Cairo’s the Nasr City district.
Last week, a confrontation between military personnel and pro-Morsi demonstrators outside the Republican Guard building left over 50 protesters killed.
Two marches will leave from Al-Istiqama Mosque in Giza and Al-Asad Ibn El-Furat Mosque in Cairo's Dokki district and will head to Giza's Nahda Square.
Al-Jazeera Mubashir Misr reported that another march is on its way to the High Constitutional Court in Cairo's Maadi district.
Earlier on Wednesday, minor scuffles were reported in front of the cabinet building in downtown Cairo after Morsi supporters marched there to denounce the newly-appointed government officials.
Pro-Morsi protesters have been staging sit-ins and demonstrations around Cairo over the past week calling for Morsi's reinstatement.
On Monday, seven people were killed and 261 injured in overnight clashes between Egyptian police and pro-Morsi demonstrators in downtown Cairo and Giza.
The violence reportedly broke out late on Monday after police forces fired teargas at Morsi supporters who had blocked the 6 October Bridge and Ramses Street in downtown Cairo.
On Tuesday, the Muslim Brotherhood issued a statement in response to the clashes, accusing the police of returning to its brutal practices prior to Egypt's January 25 revolution. The statement further warned of a possible return to a "dictatorship police state" after the "bloody coup d’etat."
