"The president is no longer able to make any political decisions now and a decision has been taken to prevent leaders loyal to the current regime from traveling overseas until the General Command of the Armed Forces are finished formulating their expected statement," it added, APA reports quting CNN.
The announcement came less than two hours after the nation's first democratically elected president offered to form an interim coalition government and as one of his aides and a Muslim Brotherhood spokesman said it appeared that a military coup was under way.
"The presidency's vision includes the formation of a coalition government that would manage the upcoming parliamentary electoral process, and the formation of an independent committee for constitutional amendments to submit to the upcoming parliament," Morsy said in a posting on his Facebook page.
He urged that his countrymen be allowed to express their opinions through the ballot box.
The posting came as protesters packed public spaces around the country to demonstrate their opposition to and support of his government. But whether his statement would stave off military intervention was not immediately clear.
As night fell Wednesday, Egyptian deployed across parts of Cairo and surrounded a pro-Morsy demonstration at a Cairo mosque.
The president himself was said to be working from a complex belonging to the country's Republican Guard, across the street from the presidential palace, according to Egyptian state media. Reuters reported that troops were setting up barricades around that facility.
Coup allegation
An aide to Morsy, Essam El Haddad, said in a Facebook posting that a coup was under way.
"For the sake of Egypt and for historical accuracy, let's call what is happening by its real name: military coup," said El Haddad, who works in the office of the assistant to the president on foreign relations.
He added, "In a democracy, there are simple consequences for the situation we see in Egypt: The president loses the next election or his party gets penalized in the upcoming parliamentary elections. Anything else is mob rule."
And a Muslim Brotherhood spokesman, Gehad El-Haddad, described what was happening as a "full military coup."
But Naguib Abadeer, a member of the opposition Free Egyptians Party, said what was under way "is not by any means a military coup. This is a revolution."
"The people have decided that Mr. Morsy was no longer the legitimate leader of Egypt," he told CNN.
Abadeer said Morsy lost his legitimacy in November, when he declared courts could not review his decrees and ousted the country's prosecutor-general. And he said Morsy's supporters in the Muslim Brotherhood "hijacked the vote of the people" by running on a religious platform, "so these were not democratic elections."
On Tuesday night, Morsy had vowed that he would not comply with an ultimatum delivered Monday by the military demanding that he enter into a power-sharing agreement.
"If the price of upholding this legitimacy is my own blood, I am, therefore, ready to sacrifice my blood for this country and its stability," he said.

He demanded the military withdraw its ultimatum and return to its barracks.
Reports of a TV studio takeover
Reuters and several other news organizations reported that Egyptian troops had "secured the central Cairo studios of state television" as the deadline approached and that staff not working on live shows had departed.
CNN has not confirmed the reports; state television denied in an on-air banner that there was any additional military presence at its studios.
Massive demonstrations for and against the former Muslim Brotherhood leader who was elected to office a year ago have been largely peaceful.
But 23 people died, health officials said, and hundreds more were injured in clashes overnight at Cairo University, the state-funded Al-Ahram news agency reported.
Protest leaders have called for nonviolence.

Egypt protesters' message to Morsy: Go Protesters: We're not going; he must go Morsy's close adviser speaks to Amanpour
Egypt's military met Wednesday with religious, national, political and youth leaders to address the crisis, Egyptian military spokesman Ahmed Ali said through his Facebook page.
Hours earlier, an opposition spokesman accused the United States of propping up Morsy out of concern for neighboring Israel.
"The hour of victory is coming," said Mahmoud Badr of the Tamarod opposition group. He predicted that the "illegitimate president" would be gone by the end of the day.
"Not America, not Morsy, not anyone can impose their will on the Egyptian people," Badr said.
