A Cairo criminal court sentenced Mohamed Badie, the Muslim Brotherhood's supreme guide, and 13 other leading members of the group to death on Monday for inciting murder in the now infamous case known in the media as "Rabaa control room."

The 14 convicted include the Muslim Brotherhood's Mahmoud Ghozlan, Saad El-Hossainy, Salah Soltan and Fathy Shehab.

The court has also set the date of 11 April to announce its verdict concerning other defendants in the case, which include Egyptian- American Mohamed Soltan, Jehad Haddad, Saad Khairat El-Shater and Gamal El-Yemani.

The court has referred the death sentences to Egypt's Grand Mufti for revision.

The referral of the sentences to the Mufti is the first step in the legal process required to enact a death sentence. The Mufti's decision is not binding. However, following his decision the court will issue a final verdict. Once a final verdict is issued, defendants can appeal.

Badie and another 13 Brotherhood figures are convicted of setting up an operation after the violent dispersal of the Rabaa Al-Adaweya protest camp in mid-August in 2013 to direct the movements of Brotherhood supporters across the country as part of plans to defy the state and spread chaos, as well as plot attacks on police stations, private property and churches.

Badie is currently standing several trials in relation to violent acts committed by supporters of ousted Islamist president Mohamed Morsi, who hails from the Brotherhood, following the police's dispersal of two pro-Morsi sit-ins in August 2013.

He was also sentenced to death before in other cases but the sentences were later reduced to life imprisonment.

The Muslim Brotherhood was designated as a terrorist organisation in November 2013 by the Egyptian government.
