Doctors in Egypt say at least 100 people have been killed and thousands wounded during clashes overnight.
The protests began when the head of the army, Abdel Fattah al-Sisi, asked people to take to the streets to show their support for the military.
Many of those who died were supporters of the ousted president, Mohamed Morsi, who were staging a sit-in at a mosque.
