Protestors are back in Cairo today, defying military orders to stay off the streets.
Supporters of former President Mohammed Morsi are demanding their leaders be put back in power.
They are taking in what the Muslim brotherhood is called a day of rage to protest more than 600 people killed this week.
Authorities announced on state television that police will turn their guns on anyone who attacks security forces or government buildings.
The army deployed armored vehicles around the city. Dozens have already died in clashes today.
The brotherhood released a statement saying the group “will not back down”.
