(CNN) -- A group supporting deposed Egyptian President Mohamed Morsy have called for a million-man march from 33 different mosques Friday following noon prayers under the banner of "Egypt against the coup," according to a statement released Thursday by the Anti-Coup Prodemocracy Alliance.
They also called on "all free people in all countries of the world to demonstrate peacefully" in support of their marches, according to the statement.
This comes after Egypt's Interior Ministry on Thursday urged pro-Morsy protesters to leave two Cairo squares and guaranteed they would have a safe exit.
The protests represent a threat to national security and traffic congestion, Information Minister Durriya Sharaf el-Din said Wednesday. Interim Interior Minister Mohamed Ibrahim was authorized to take "all necessary measures to face these dangers and end them," el-Din said.
The statement is being widely interpreted by local media outlets as a green light for security forces to disperse the thousands of protesters at the sit-ins at squares in Rabaa al-Adawiya and Nahda Masr.
