An army source said on Friday that curfew violations will not be taken lightly, the Egyptian state television reported.
He called on all citizens to stay home after 7 p.m. as the country faces a new wave of violence.
Egypt announced a nationwide month-long state of emergency and imposed a curfew in 12 governorates on Wednesday following the death of over 90 people in the crackdown against supporters of ousted President Mohamed Mursi.
The number of deaths since Wednesday has jumped to over 600 while injuries are estimated at thousands.
