Thousands of Mohamed Morsi's supporters have rallied in Cairo against the military, as supporters and opponents of the deposed Islamist president clashed elsewhere in Egypt.
The rallies on Friday come nearly a month after the August 14 crackdown by security forces on two pro-Morsi protest camps in Cairo that led to clashes in which hundreds of people were killed, the worst carnage in Egypt's recent history.
"Either we recover their rights, or we die like them," protesters chanted of those who lost their lives in the crackdown, as they marched toward Rabaa al-Adawiya Square, the site of one of those camps.
An AFP correspondent said soldiers used barbed wire to block roads to the square in the Nasr City district, with troops in helmets and carrying shields standing guard.
Protesters chanted "Abdel Fattah is the butcher", referring to army chief Abdel Fattah al-Sisi, as they passed a government building guarded by soldiers.
