The National Salvation Front says Morsi’s government is “authoritarian” following deadly clashes.
“The Salvation Front completely sides with the people and its active forces’ calls to topple the authoritarian regime and the Muslim Brotherhood’s control,” it said, urging Egyptians to stage peaceful protests.
It demanded Morsi’s trial for crimes of “killings and torture” and ruled out dialogue with the presidency until “the bloodletting stops and those responsible for it are held accountable”.
Police clashed with protesters outside Cairo’s presidential palace on Friday night, leaving at least one person dead. Television footage, meanwhile, showed police beating and dragging a naked man into an armoured vehicle.
In all, more than 50 people were injured on Friday, including at least five policemen.
