Egypt's Muslim Brotherhood says at least 2,200 people have been killed and 10,000 others injured in the crackdown by the Egyptian security forces on protest sit-ins held by the supporters of ousted President Mohamed Morsi in Cairo.
The Brotherhood said the figure was provided by Rabaa hospital on Wednesday.
Meanwhile, the Egyptian Interior Ministry claimed that 4 soldiers were killed in the clashes between the protesters and the security forces.
The Egyptian state TV has announced that the protesters have been evacuated from their camps in Rabaa al-Adawiya Mosque and Nahda Square by the security forces.
Police reportedly used tear gas, armored cars and bulldozers to disperse Morsi's supporters.
The Egyptian army had earlier warned of taking action against the supporters of the ousted president.
Egyptian authorities have grounded all trains to prevent protesters leaving the capital.
The Egyptian security officials said that some 200 supporters of Morsi who were captured in Rabaa area were carrying weapons.
Egypt's Interior Ministry also said a number of Muslim Brotherhood leaders have been arrested.
Brotherhood leaders condemned the “massacre,” calling on the Egyptians to take into the streets and protest against the spiraling violence.
Egypt has plunged into unrelenting string of violence since General Abdel Fattah al-Sisi, the head of the Egyptian army pushed aside Morsi, the country's first democratically elected president, and declared chief Justice of Egypt’s Supreme Constitutional Court, Adly Mansour as the interim president.
Hundreds of protesters, mostly Morsi’s supporters, have been killed or wounded during the unrelenting violence that has erupted since the removal of Morsi.
