Cairo Criminal Court upheld on Sunday death verdicts for 20 of 156 defendants accused of storming Kerdasa police station in Giza, killing the Sheriff, 12 officers and a police conscript.
The incident dates back to July 2013, following the ousting of former President Mohamed Morsi after mass protests took place on June 30 that year.
Several militants stormed the Kerdasa police station and opened fire against security members stationed there, in protest of the dispersal of the Muslim Brotherhood sit-ins at Rabaa and al-Nahda.
In the aftermath of the incident, 188 defendants were referred to the criminal court for their roles in the incident and received death sentences, however 156 of them decided to appeal.
