The streets of Cairo are quiet overnight Thursday as residents respect a dawn to dusk curfew, but that could change in a few hours.
The Muslim Brotherhood has called for a nationwide march- a Friday of Anger- to protest the army crackdown earlier this week in which at least 620 people were killed during two Muslim Brotherhood protests in Cairo.
The violence that's divided the country between those who support Islamist leader Mohamed Mursi and those who support his outster has sparked international criticism.
Members of the United Nations Security Council are calling for calm.
"The view of council members is that it is important to end violence in Egypt, that the parties exercise maximum restraint. And there was a common desire on the need to stop violence and to advance national reconciliation."
But some diplomats feel the Muslim Brotherhood will try to use the crackdown unfairly to their advantage.
The Egyptian ambassador to the UK said the Brotherhood wanted the violence so they could portray themselves as victims.
"Yesterday, this number of killings and this mass of violence I think they got what they want. Everybody say 'really?' I says 'yes'. They show that they are victims and I think also what they want, they don't want to diffuse this protest except with this way. This is the way they want it and I think they achieved what they want," said Egyptian ambassador to the UK Ashraf el-Kholy.
Earlier Thursday, residents in Cairo cleaned up broken glass from storefronts and removed debris from the streets.
How and when the issue will be resolved remains unclear, with both sides staunchly resolute in their convictions.
Leftist groups have also called for protests to be held on Friday.
