Interior Minister Mohamed Ibrahim said pro-Mursi sit-ins will be "dealt with soon".
"God willing, it will be broken up in a way that does not cause losses," Ibrahim said. "But, God permitting, it must end. We hope that they come to their senses...And join their political process.
"With regards to the timing...To disperse the protesters, there is complete coordination between us and the armed forces," Ibrahim told a news conference.
