saying he welcomes help from the Muslim Brotherhood to “build the 
nation”. 300 members of the movement are already behind bars and new 
warrants are being issued.

  UPDATES on Egypt protests
  
  Adli Mansour, 67, was one of those who drafted the election law
  which regulated the 2012 campaign, bringing the now ousted Morsi
  to power. At the same time, the judiciary he was part of, was one
  of Morsi’s main opponents, trying not to let the ousted leader
  push through constitution change.

The interim Egyptian leader has been out of the spotlight
  throughout much of his long career in the judiciary. Mansour
  became Deputy Justice at the Supreme Constitutional Court in
  1992, under Mubarak.  In May he was appointed by Morsi as
  Chief Justice, but did not take office until July 1, when his
  predecessor retired. He was sworn in as head of the
  Constitutional Court on Thursday minutes before the procedure
  which made him interim President.
  
  At the Thursday swearing-in ceremony, he hailed the protesters
  and the armed forces and also addressed the Muslim Brotherhood.
  
  "
The Muslim Brotherhood group is part of this people and are
  invited to participate in building the nation as nobody will be
  excluded, and if they respond to the invitation, they will be
  welcomed," Adli Mansour said, as cited by Reuters.

Despite Mansour’s benevolent comments concerning the Muslim
  Brotherhood, the military, who ousted Morsi, appear to be not as
  tolerant. They have presumably put the ex-president and his aides
  in the same prison with Mubarak, according to local media. Arrest
  warrants have also been issued for 300 members of the Muslim
  Brotherhood.
  
  Names of some top officials are on the list, including the Muslim
  Brotherhood leader, Mohamed Badie, his deputy, Khairat el-Shater,
  together with the head of the Muslim Brotherhood’s Freedom and
  Justice Party, Saad El-Katatni. 
  Mohammed Badie was arrested on Wednesday night in a resort
  village in Marsa Matrouh, a Mediterranean coastal city north west
  of Cairo, reported AP citing Egyptian officials. He had been
  staying in a villa owned by a businessman with links to the
  group.

Though the Tahrir crowd erupted into jubilant cheers following
  the news of  Morsi’s ousting, the country remains deeply
  divided between Morsi’s opponents and supporters, with at least
  11 people killed and over 500 injured in clashes, following the
  military’s announcement.
  
  Egyptian President Mohamed Morsi was ousted by the military late
  on Wednesday, with security forces forbidding him from leaving
  the country, arresting a number of top Muslim Brotherhood
  officials, and blacking out broadcasts from a number of media
  outlets. Four days of multi-million strong anti-government
  protests preceded the events.
  
  Morsi condemned the actions of the armed forces, describing them
  as a coup and urging Egyptians not to accept it. 
  Most of the Arab Gulf nations embraced Morsi’s removal. As for
  response from the West, it’s more cautious, with world leaders
  urging the Egyptian military towards non-violence and a return to
  democracy.
