Morsi’s supporters on Sunday held marches to Rabia al-Adawiya Square and Al-Nahda Square close to Cairo University, demanding his return to power.
They also erected barricades and set up checkpoints across Cairo, where tens of thousands of them blocked the main road leading to the international airport.
Anti-Morsi demonstrators gathered in Cairo’s iconic Liberation Square and around the presidential palace.
Opponents of the ousted president also took to the streets in Alexandria on the coast of the Mediterranean Sea and in other major cities across the North African country.
Meanwhile, Egyptian media reported on Sunday that Social Democratic lawyer Ziaad Bahaa el-Din has been offered to become Egypt’s new prime minister.
Reports also said leading opposition figure Mohamed ElBaradei is also set to be appointed as Egypt’s vice-president. However, the appointments have not been officially confirmed yet.
Leader of Egypt’s Salafist Nour Party, Younes Makhyoun has dismissed the choice of Bahaa el-Din as interim prime minister and objected to plans to appoint ElBaradei as vice-president. He added that a politically-neutral person should become premier.
On Saturday, the official MENA news agency said that Egyptian interim president Adly Mansour had appointed ElBaradei as interim prime minister, but his office later denied that any final decision had been taken.
Earlier on Sunday, the Nour Party said it would not accept ElBaradei as premier.
On July 3, Egypt’s army commander General Abdel Fattah al-Sisi ousted Morsi, who had taken office in June 2012, and dissolved the country’s constitution.
Morsi is reportedly being held “preventively” by the army. Senior military officials say he might face formal charges over accusations made by his opponents.
Meanwhile, Russia’s President Vladimir Putin has expressed concern over the situation in Egypt, saying, “Syria is already in the grips of a civil war, unfortunately enough, and Egypt is moving in that direction.”
Meanwhile, Egypt’s medical sources say at least 34 supporters of the country’s ousted President Mohamed Morsi have been killed by the security forces during protests in the capital Cairo.
The country’s Muslim Brotherhood have confirmed the report.
