Former Egyptian president Mohamed Morsi was sentenced to death on Tuesday over a prison break in 2011, a verdict that confirmed a preliminary judgement issued in May.
The verdict can be appealed.
The court sentenced a total of 99 people, including Morsi, to death. Only six who received the death sentence are in custody. While 93 others were sentenced in absentia, as they are currently at large.

On 16 May, the court issued a preliminary death sentence against Morsi and 105 other defendants in the jailbreak case, after which their papers were referred to the grand mufti, a senior Muslim cleric, for a consultative review as required by Egyptian law.
The mufti's advice regarding the death sentence is not legally binding.
