In the capital, armoured personnel carriers were deployed and security forces threw tear gas and fired in the air to prevent anti-regime demonstrators from reaching Tahrir Square, the symbolic center of the 2011 uprising.

Demonstrators supporting the post-coup interim goverment had gathered in Tahrir. Some called for the head of the military, General Abdel Fattah al-Sisi, to run for the Presidency.

Anti-regime protesters marched in more than 30 neighborhoods and were confronted in several locations by security forces.

Meanwhile, Ansar Beit al-Maqdis claimed responsibility for four bombs in Cairo on Friday that killed at least eight people.

On Saturday, an explosion at a Suez police camp injured four people.

The Deputy Interior Minister said the blast was from a car bomb.
