Army officers “all have powers of legal arrest,” it says.
The military, which ruled Egypt between former president Hosni Mubarak’s ouster in February 2011 to Morsi’s election in June 2012, has sought to remain neutral in the political crisis.
But it has warned it “will not allow” the situation to deteriorate, and urged both sides to have a dialogue.
Army tanks and troops have since Thursday been deployed around Morsi’s presidential palace. But they have not confronted thousands of protesters who have gathered there every night. The opposition, made up of secular, liberal, leftwing and Christian groups, has said it will escalate its protests to scupper the referendum.
It views the new constitution, largely drawn up by Morsi’s Islamist allies, as undermining human rights, the rights of women, religious minorities, and curtailing the independence of the judiciary.
