Fifty-one people, mostly Mohamed Morsi loyalists, were killed in Egypt while rallying in favour of the ousted president, as the new rulers announced fresh elections by early 2014.
Morsi’s Muslim Brotherhood, which has led demonstrations against Wednesday’s overthrow of the Islamist leader, called for an “uprising,” saying troops and police “massacred” its supporters during dawn prayers in Cairo Monday.
Amid the widening chasm in the restive country, interim president Adly Mansour issued a decree setting a timetable for a referendum on an amended constitution and parliamentary elections by the end of January.
He will announce the date for presidential elections after the new parliament convenes, according to a draft of the 33-article decree published by the official MENA news agency.
The carnage outside the elite Republican Guards’ headquarters has further delayed Adly’s efforts to name a new prime minister, as the loose opposition coalition that backed Morsi’s ouster lost a key Islamist party.
The Brotherhood released the names of 42 people killed in the incident, as the interior ministry and military said two policemen and a soldier were also killed.
The military blamed “terrorists”, while witnesses, including Brotherhood supporters at the scene, said security forces fired only warning shots and tear gas, and that “thugs” in civilian clothes carried out the shootings.
The United States called on the Egyptian army to exercise “maximum restraint”, while also condemning “explicit” Brotherhood calls to violence.
The Islamist movement’s political arm, the Freedom and Justice Party (FJP), had called for “an uprising by the great people of Egypt against those trying to steal their revolution with tanks” because of Monday’s killings.
It urged “the international community and international groups and all the free people of the world to intervene to stop further massacres… and prevent a new Syria in the Arab world”.
UN Secretary-General Ban Ki-moon condemned the latest wave of bloodshed in Egypt, calling for an independent inquiry.
The Secretary-General “calls on all Egyptians to be mindful of the precarious path the country is now on and to do everything possible to avoid further escalation,” Ban’s spokesman Martin Nesirky said.
According to Adly’s decree, a panel representing political, religious and security services will agree final amendments to the constitution suspended on Morsi’s ouster and put it to referendum within five months.
Parliamentary elections would be completed in less than three months.
White House spokesman Jay Carney said an immediate cutoff in military aid to Egypt “would not be in our best interests”, when asked whether Washington was reconsidering the more than $1 billion–mostly military aid–it provides annually.
In response to the “massacre”, the conservative Islamist Al-Nur party, which won almost a quarter of the votes in 2011-2012 parliamentary elections and had backed the army’s overthrow of Morsi, said it was pulling out of talks on a new government.
Grand Imam Ahmed al-Tayyeb of the Cairo-based Al-Azhar, Sunni Islam’s highest seat of learning, said he would “remain in seclusion” until the bloodletting ends “and those behind it take responsibility”.
Mansour, a top judge before his appointment as interim president, had ordered a judicial commission of inquiry into the killings.
Witnesses say Islamists hurled stones at the security forces who responded with tear gas and live rounds.
Emergency services chief Mohammed Sultan told the official MENA news agency at least 51 people were killed and 435 wounded.
Emotions ran high as people searched for the names of missing loved ones on a list of the dead in hospital, where dozens of bodies were laid on the bloody floor of a makeshift morgue.
The army warned it would not allow anyone to threaten national security, urging protesters to stay away from military installations and to end their sit-ins.
A security official said prosecutors later ordered the closure of the FJP’s Cairo headquarters after police discovered weapons they alleged would be used against Morsi opponents.
International condemnation of Monday’s bloodshed poured in, with Germany expressing “shock” at the violence, Turkey calling it an attack on “humanity” and Brotherhood backer Qatar urging “self-restraint” and “unity”.
It followed another day of duelling demonstrations across the Arab world’s most populous nation of 84 million in an escalating crisis some fear could be exploited by extremist groups.
Morsi’s single year of turbulent rule was marked by accusations he failed the 2011 revolution that ousted autocratic president Hosni Mubarak by concentrating power in Islamist hands and letting the economy nosedive.
The military, which overthrew Morsi after millions took to the streets on June 30 demanding that he resign, has come under mounting international pressure to swiftly install a civilian administration to oversee a rapid return to elected government.
Before the latest violence, Mansour aides had said he was leaning towards centre-left lawyer Ziad Bahaa Eldin as premier with ElBaradei as vice president, and that an announcement would be made on Monday.
