The swift moves raise perceptions of a revenge campaign against the Brotherhood.
The National Salvation Front, the top opposition political group during Morsi's presidency and a key member of the coalition that worked with the military in his removal, criticized the moves, saying, "We totally reject excluding any party, particularly political Islamic groups."
The Front has proposed one of its top leaders, Mohammed ElBaradei, to become prime minister of the interim Cabinet, a post that will hold strong powers since Mansour's presidency post is considered symbolic. ElBaradei, a Nobel Peace laureate who once headed the U.N. nuclear watchdog agency, is considered Egypt's top reform advocate.
"Reconciliation is the name of the game, including the Muslim Brotherhood. We need to be inclusive," Munir Fakhry Abdel-Nour, a leading member of the group, told The Associated Press. "The detentions are a mistake."
He said the arrests appeared to be prompted by security officials' fears over possible calls for violence by Brotherhood leaders. There may be complaints against certain individuals in the Brotherhood "but they don't justify the detention," he said, predicting they will be released in the coming days.
Morsi has been under detention in an unknown location since Wednesday night, and at least a dozen of his top aides and advisers have been under what is described as "house arrest," though their locations are also unknown.
Besides the Brotherhood's top leader, General Guide Mohammed Badie, security officials have also arrested his predecessor, Mahdi Akef, and one of his two deputies, Rashad Bayoumi, as well as Saad el-Katatni, head of the Brotherhood's Freedom and Justice Party, and ultraconservative Salafi figure Hazem Abu Ismail, who has a considerable street following.
Authorities have also issued a wanted list for more than 200 Brotherhood members and leaders of other Islamist groups. Among them is Khairat el-Shater, another deputy of the general guide who is widely considered the most powerful figure in the Brotherhood.
The arrest of Badie was a dramatic step, since even Mubarak and his predecessors had been reluctant to move against the group's top leader. The ranks of Brotherhood members across the country swear a strict oath of unquestioning allegiance to the general guide, vowing to "hear and obey." It has been decades since a Brotherhood general guide was put in a prison.
Badie and el-Shater were widely believed by the opposition to be the real power in Egypt during Morsi's term. Badie was arrested late Wednesday from a villa where he had been staying in the Mediterranean coastal city of Marsa Matrouh and flown by helicopter to Cairo, security officials said, speaking on condition of anonymity because they were not authorized to talk to reporters.
Mahmoud, the top prosecutor, said he was opening investigations into the killing of protesters during Morsi's rule. He ordered el-Katatni and Bayoumi questioned on allegations of instigating violence and killing and put travel bans on 36 others, a sign they, too, could face prosecution. He also took steps toward releasing an activist detained for insulting Morsi.
