CAIRO - Egypt’s interior ministry on Thursday promised Mohamed Morsi’s supporters ‘safe exit’ if they quickly leave their Cairo protest camps, as police prepared to disperse them amid international appeals for restraint.

The call to disperse, which came after police commanders discussed how to carry out orders from the military-installed interim government to end the protests, was immediately rejected by the demonstrators.

Diplomatic efforts to avoid further bloodshed picked up pace, with EU Middle East envoy Bernardino Leon and German Foreign Minister Guido Westerwelle both arriving in Cairo to urge the rival camps to find common ground.

An interior ministry statement called “on those in Rabaa al-Adawiya and Nahda squares to let reason and the national interest prevail, and to quicky leave.”

The ministry “pledges a safe exit and full protection to whoever responds to this appeal,” the statement added.

But Allaa Mostafa, a spokeswoman for the Anti Coup Alliance organising demonstrations demanding the reinstatement of the deposed Islamist president, told AFP “we are going to continue our peaceful sit-ins and our peaceful protests.”

Ministers had ordered police to end sit-ins and marches by Morsi’s Islamist supporters, saying they amounted to a “national security threat.”

The orders raised fears of new violence, less than a week after 82 people were killed in clashes at a pro-Morsi rally in Cairo.

The international community, which has expressed mounting concern over the violence since Morsi’s July 3 ouster, warned against further bloodshed. The German foreign minister, who arrived in Cairo on Wednesday, urged both sides to remain peaceful and seek an inclusive solution.

“I am here to encourage all political forces to engage in dialogue,” he said at a press conference on Thursday with his Egyptian counterpart, Nabil Fahmy.

Later, he was scheduled to meet interim president Adly Mansour and representatives of Morsi’s Muslim Brotherhood and other political parties.

EU envoy Leon also landed in Cairo on Wednesday, to follow up on three days of intensive diplomacy by the bloc’s foreign policy chief, Catherine Ashton.

Meanwhile, US Secretary of State John Kerry said Thursday the Egyptian army, which deposed president Mohamed Morsi, had intervened at the request of millions to protect democracy and had restored it.

Kerry made the remarks in a interview in Pakistan where he earlier congratulated the new government on an historic transition of democratic power in a country long dominated by the military.

He was asked by Geo television why the United States had not taken a clear position on military intervention against Morsi’s democratically elected government.

“The military was asked to intervene by millions and millions of people, all of whom were afraid of a descendance into chaos, into violence,” Kerry told Geo.

“And the military did not take over, to the best of our judgement - so far. To run the country, there’s a civilian government. In effect, they were restoring democracy,” he added.

The interviewer questioned him over allegations that Egyptian troops have shot dead people in the streets.

“Oh, no. That’s not restoring democracy, and we’re very, very concerned... I’ve been in touch with all of the players there. And we have made it clear that that is absolutely unacceptable, it cannot happen,” Kerry said.

He said the United States was working with the European Union and other countries to see if the troubles in Egypt could be resolved peacefully.

“But the story of Egypt is not finished yet, so we have to see how it unfolds in the next days,” he said.

The US State Department called on the interim authorities to “respect the right of peaceful assemblies.” “That obviously includes sit-ins,” spokeswoman Marie Harf told reporters.

British Foreign Secretary William Hague called for “an urgent end to the current bloodshed” and the release of Morsi, in a phone call to interim vice president Mohamed ElBaradei, the Foreign Office said.

And Amnesty International condemned the cabinet order as a “recipe for further bloodshed.”

In Rabaa al-Adawiya, the mood was calm after the cabinet’s announcement. Thousands of protesters have been camped out in a tent city at the square. 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”.

Accusing Morsi supporters of bearing arms, he told AFP: “It is clear the interior ministry has been given the green light to take the necessary measures within legal bounds.”

The interim government also faces an increase in militant attacks in the restive Sinai peninsula, where gunmen on Thursday shot dead a policeman in the northern town of El-Arish, security officials said.

Much of the Egyptian media expressed support for the government’s decision, with some saying the interim administration had received “the people’s mandate” in demonstrations last Friday backing Morsi’s overthrow.

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

Further raising tensions on Wednesday, judicial sources said several top Brotherhood leaders would be referred to trial for incitement to murder.

Supreme guide Mohamed Badie, who is in hiding, and his jailed deputies Khairat al-Shater and Rashad Bayoumi, stand accused of inciting the killing of demonstrators outside Brotherhood headquarters on the night of June 30.

Morsi himself has been formally remanded in custody on suspicion of offences when he broke out of prison during the 2011 revolt that toppled president Hosni Mubarak.

He was detained hours after the coup and is being held at an undisclosed location, where the EU foreign policy chief met him on Tuesday, later telling reporters he was “well.”
