Thousands marched in Cairo late Sunday to condemn the killing of dozens of pro-Morsi protesters a day a earlier.
Marchers chanted anti-military and anti-police slogans in the capital's Nasr City district where deadly clashes took place on Saturday between security forces and Morsi supporters, state news agency MENA reported.
Traffic was brought to a standstill, but the march passed off peacefully, MENA added.
Morsi's Muslim Brotherhood and the interior ministry have blamed each other for igniting the bloodshed on Saturday near the pro-Morsi protest at the Rabaa Al-Adawiya mosque.
Egypt has been rocked by unrest since Islamist president Mohamed Morsi was ousted on 3 July following nationwide protests against his rule. Scores have been killed and hundreds wounded in violence between rival factions.
