CAIRO - Supporters of ousted President Mohamed Morsi called for protests on Friday and Egyptians prayed there would be no repeat of clashes that have killed more than 90 people in the last week and left the Arab world's biggest nation bitterly divided.
More than a week after the army toppled Egypt's first elected leader on a wave of demonstrations, Morsi's Muslim Brotherhood movement wants people to join it on the streets to push for him to be reinstated, an aim that now seems in vain.
The streets of Cairo were quiet on Friday morning, with separate demonstrations by Morsi supporters and opponents expected later in the day, the weekly Muslim prayer day.
Egypt's interim prime minister will start contacting candidates for cabinet ministries on Sunday and Monday with a view to having the cabinet sworn in by the end of next week, he told Reuters on Friday.
Hazem el-Beblawi, a liberal economist and former finance minister, was named to head the cabinet after the army removed Morsi. He is trying to assemble an interim government to lead the country under an army "road map" to restore civilian rule.
Officials say Morsi is still being held at the Republican Guard compound in Cairo, where troops killed 53 Islamist protesters on Monday
in a clash that intensified anger his allies already felt at the military's decision to oust him.
Four members of the security forces were also killed in a battle the military says was started by terrorists. Morsi's supporters call the incident a "massacre" and say those who died were praying peacefully when troops opened fire.
Many of Egypt's 84 million people have been shocked by the shootings, graphic images of which have appeared on state and private news channels and social media. The incident came just three days after 35 people were killed in clashes between pro- and anti-Morsi demonstrators across the country.
"It's a very hard time for Egyptians, to see footage of blood and violence during the holy month of Ramadan, and everyone I speak to says the same thing," said Fateh Ali, a 54-year-old civil servant in Cairo.
"I really hope the situation gets resolved soon. I don't think we can afford this economically or psychologically."
The Brotherhood believes it is the victim of a brutal military crackdown, evoking memories of when it was suppressed under longtime autocratic leader Hosni Mubarak, who was toppled in a popular uprising in 2011.
But many of its opponents blame Islamists for the violence, and some have little sympathy for demonstrators who died, underlining how deep the fissures in Egyptian society are.
The unrest has also raised fear over security in the lawless Sinai peninsula bordering Israel and the Palestinian Gaza Strip. One Egyptian policeman was killed and another wounded early on Friday
when militants fired rocket-propelled grenades at checkpoints in the Sinai town of El Arish.
Egyptian state media said police arrested three Palestinian militants conducting attacks in Sinai.VIGIL, SONGS FOR THE DEAD
Outside the Rabaa Adawiya mosque in northeastern Cairo, thousands of Brotherhood supporters gathered late on Thursday to mourn the dead in Monday's violence, the deadliest since Mubarak was toppled apart from a 2012 soccer stadium riot.
Women wailed and men cried as they watched a large screen showing graphic footage of hospital scenes immediately after the shooting, with corpses on the floor and medics struggling to cope with the number of bloodied casualties being carried in.
Hundreds of Egyptian flags fluttered in the evening breeze. Songs of defiance were sung.
Many thousands of Islamists have camped out in the area, braving searing heat and, since Wednesday, daytime fasting during Ramadan.
It has become the de facto base of the Brotherhood, whose leaders live under the threat of detention after the public prosecutor ordered their arrests earlier in the week.
Judicial sources say authorities are expected to charge Morsi in the coming days, possibly for corruption or violence. Prosecutors are also taking a fresh look at an old case over a 2011 prison break when Morsi was among Brotherhood figures who escaped after being rounded up during anti-Mubarak protests.
The detentions and threats of arrest have drawn concern from the United States, which has walked a diplomatic tightrope to avoid calling Morsi's ouster at the hands of the powerful Egyptian military a coup.
US law bars aid to countries where a democratic government is removed in a coup. Washington, which gives Egypt's military $1.3 billion in aid each year, has said it is too early to say whether the Egyptian events meet that description.
The Egyptian army said it was enforcing the nation's will after millions of people, fed up at economic stagnation and suspicious of a Brotherhood power grab, took to the streets at the end of June to demand his resignation.
State Department spokeswoman Jen Psaki said on Wednesday Morsi's government "wasn't a democratic rule."
Her words were warmly received by the interim government
and swiftly denounced by the Brotherhood. On Thursday, Psaki expressed concern over the crackdown on Brotherhood leaders.
"If politicized arrests and detentions continue, it is hard to see how Egypt will move beyond this crisis," she said.ALARM OVERSEAS
Underlining the level of concern overseas at Egypt's crisis, two U.S. Navy ships patrolling in the Middle East moved closer to Egypt's Red Sea coast
in recent days, in what appeared to be a precautionary move following Mursi's ouster on July 3.
The United States often sends Navy vessels close to countries in turmoil in case it needs to protect or evacuate US citizens or give humanitarian assistance.
Rich Gulf states have thrown Egypt a $12 billion lifeline in financial aid, which should help it stave off economic collapse.
Germany's Foreign Ministry on Friday urged all political parties in Egypt to refrain from violence or threats of violence, and called on Egyptian authorities to allow an international organization access to ousted president Mohamed Morsi.
"All forms of political persecution would be extremely damaging for the future of Egypt. We call for an end to the restrictions on Mr Morsi, and we also urge all political powers, in particular the leaders of the Muslim Brotherhood, to refrain from all forms of violence or threat of violence," a ministry spokesman said.
He said Germany wanted a trustworthy, neutral international organization to be allowed access to Morsi.
More than two years of turmoil has scared away tourists and investors, shriveled hard currency reserves and threatened its ability to import food and fuel.
Crucial to longer-term stability will be holding new parliamentary and presidential elections, which the transitional authorities are hoping to achieve in a matter of months.
Adli Mansour, the interim president named by the general who removed Morsi, has announced a temporary constitution, plans to amend it to satisfy parties' demands and a faster-than-expected schedule for parliamentary elections in about six months.
He also has named liberal economist Hazem el-Beblawi as interim prime minister. Beblawi held his first meetings with political leaders on Wednesday and told Reuters that he expected the transitional Cabinet to be in place early next week.
Negotiations are difficult, with the authorities trying to attract support from groups that range from secularists to ultra-orthodox Muslims, nearly all of whom expressed deep dissatisfaction with elements of the interim constitution.
