Cairo Criminal Court sentenced on Saturday 77 supporters of ousted president Mohamed Morsi to 10 years in prison and 27 others to seven years in their retrial over charges of murder and rioting.
The defendants were originally sentenced in May 2014 but they appealed the court decision and the Court of Cassation ordered a retrial.
The 104 were arrested in July 2013 following a protest in Cairo's Al-Zaher district, after the ouster of Morsi, who hails from the Muslim Brotherhood, following mass protests.
They were charged with attempted murder, inciting murder, threatening violence, and sabotaging private and public property.
The protests led to the killing of Ahmed Salah El-Bassiouny, for which the defendants were accused of murder.
The Muslim Brotherhood was designated as a terrorist organisation by Egypt's government in late 2013.
