As supporters of ousted Egyptian president Mohammad Mursi were pledging to defy a crackdown ordered by the army-installed interim government, Egypt’s interior ministry called on protesters to disperse promising them safe exit.
  
Mursi's backers said they would hold a "march of the millions" on Friday, and denounced the orders given to police by the interim cabinet to end their Cairo sit-ins.

"The national alliance supporting legitimacy and defying the coup calls upon all the free people of the world to demonstrate peacefully in (an) 'Egypt against the coup' march of the millions," a coalition of Mursi loyalists said in a statement. It denounced the government's call for its protests to be broken up and urged "all honorable military and police forces not to direct their bullets at their brothers and sisters of the Egyptian people."

Egypt’s interior ministry, however, released a statement urging Mursi supporters to evacuate their Cairo protest camps, promising them a "safe exit."
  
The ministry "calls on those in Rabaa al-Adawiya and Nahda squares to let reason and the national interest prevail, and to quicky leave," it said in a statement. The ministry "pledges a safe exit and full protection to whoever responds to this appeal," the statement added.
  
EU's Middle East envoy and German Foreign Minister Guido Westerwelle arrived in Cairo to urge the rival camps to avoid bloodshed and find common ground.
The German foreign minister urged both sides to remain peaceful and seek an inclusive solution. He was due to be joined by EU envoy Bernardino Leon, who was to follow up on three days of intensive diplomacy by the bloc's foreign policy chief Catherin Ashton.
  
Earlier in a statement, the cabinet said: "The continuation of the dangerous situation in Rabaa al-Adawiya and Nahda squares, and consequent terrorism and road blockages, are no longer acceptable given the threat to national security,".
  
"The government has decided to take all necessary measures to confront and end these dangers, and tasks the interior minister to do all that is necessary in this regard, in accordance with the constitution and law."
  
The interior ministry had already warned that the demonstrations would be dispersed "soon," but without saying when or how. Foreign trade minister Munir Fakhry Abdel Nur said Wednesday's statement did not "give room for interpretation".

More than 250 people have been killed since the army ousted him following nationwide protests against his single year in power.
