Violence erupts in Sinai
In the lawless desert of the Sinai, where al Qaeda affiliates have long had a foothold, violent attacks erupted after Morsy's removal.
On Sunday, armed men blew up a pipeline transporting natural gas to Jordan, an ally of Israel and the United States, said a senior Egyptian intelligence officer, who asked not to be named.
Such attacks had ceased when Morsy was president. Before that, armed groups destroyed pipelines every few months, he said.
State-run EgyNews reported Sunday that three police officers in northern Sinai were shot and wounded while on duty when someone in an unmarked car fired shots at them and sped away.
It is unclear whether the attacks were a reaction to events in Cairo.
Morsy's opponents -- who got what they wanted when the military toppled him in a coup Wednesday -- will protest "to finalize the great victory" they started on June 30, activist group Tamarod said.
Egyptian police are finishing the work the military started, taking into custody the Brotherhood's leaders. Officers continue to follow up on hundreds of arrest warrants.
Mohamed Tawfik, the Egyptian ambassador to the United States, told CNN Sunday that discussions about choosing a prime minister are ongoing.
"This is something for the Egyptians themselves to decide," Tawfik said when asked if U.S. officials had indicated their support for ElBaradei. "The important thing is for this process to be inclusive and for there to be a general agreement on whoever will be named as prime minister."
State-run Nile TV reported Sunday night that Tamarod and al-Nour party members were meeting to reach a consensus over who will be the new prime minister.
The 'second revolution'
Wednesday's coup was the culmination of weeks of efforts by Morsy's opponents to push him out. They said 22 million people had signed petitions calling for him to step down -- more than had voted for him in the 2012 election -- and followed up with days of protests that attracted massive crowds.
Morsy's supporters countered with rallies in favor of his government. At times, bloody clashes ensued. Dozens were killed.
On July 1, the military issued a 48-hour ultimatum demanding that Morsy form a power-sharing government with his opponents. The end of Morsy's rule came on Wednesday, when his conciliatory gestures failed to placate the military.
Egypt's experience with democratic governance was short for a country whose history can be measured in millennia. "Either we risk a civil war or ... take extra constitutional measures to ensure that we keep the country together," said ElBaradei, explaining the military's conundrum. "This is a recall, and it is nothing novel."
But Morsy failed to fix the nation's ailing economy or stop spiraling crime, both of which worsened during his tenure. He was seen by many as increasingly autocratic.
Human Rights Watch has said Morsy had perpetuated abusive practices that Mubarak had established, molding them to his own purposes and adding to them. These included the trial of civilians by military courts, allowing police brutality and the suppression of critical voices.
Adly Mansour, head of the country's Supreme Constitutional Court, was sworn in Thursday as interim president.
He dissolved Egypt's upper house of parliament, the Shura Council, and appointed a new head of intelligence, state TV said.
The Egyptian army has promised a path to new elections.
Egypt is pivotal
The chairman of the Muslim Brotherhood in Jordan warned that the Egyptian military coup might return terrorism and extremism to the region.
"What happened in Egypt will weaken our efforts of trying to convince the people that democracy is the only way to achieve their freedom and the social justice they seek," Sheikh Hamam Saeed said. "It will also make people lose faith in democracy."
Turkish Prime Minister Recep Tayyip Erdogan called coups "evil" on Sunday.
