Nine people were executed on Monday over their involvement in an attack on Giza’s Kerdasa police station in August 2013 that killed several policemen, sources said.

The execution was carried out at Wadi Al-Natrun prison in the early hours of Monday.

Monday’s execution comes nearly three years after Egypt’s Court of Cassation upheld death sentences against 20 defendants after a Cairo Criminal Court sentenced the defendants to death in a retrial in 2017.

The retrial followed a 2014 mass trial that saw preliminary death sentences against 183 people.

Prosecutors charged the defendants with storming the Kerdasa police station in Giza on 14 August 2013, killing 12 policemen and two civilians and mutilating their bodies, attempting to murder 10 other policemen and destroying the police station.

The defendants were also charged with torching several police vehicles and being in possession of heavy firearms during the attack.

The attack on the station followed the forced dispersal of sit-ins in support of late ousted Islamist president Mohamed Morsi in Cairo in August 2013.
