The Cairo Criminal Court has sentenced 102 Muslim Brotherhood supporters to 10 years in prison, with two others receiving seven years, reported state media.
The defendants were all found guilty of various charges relating to murder, rioting and using force against police, vandalism, and joining a banned group which threatens national security.
The 104 defendants had been arrested in July 2013, following the ouster of deposed Islamist President Mohammed Morsi.
The protests, which occurred in Cairo’s Al-Zaher district, allegedly turned violent and led to the death of Ahmed Salah El-Bassiouny, for which the defendants were charged with killing.
Last week, a court sentenced 683 Muslim Brotherhood supporters to death on various charges relating to violence in Minya. Protests have been held by the group, which was designated a terrorist organization in 2013, since July 2013.
