An Egyptian court has sentenced 183 people to death over the killing of 15 policemen in violence that engulfed the country after the 2013 ouster of Islamist President Mohammed Morsi.

Monday's verdict came at the end of one of several mass trials in Egypt that have sparked an international outcry over the sentencing of hundreds of defendants on similar charges.

Many of the death sentences were later overturned on appeal, and in one incident, a judge was removed.

The suspects in Monday's proceedings were rounded up for attacking a police station in the village of Kirdasah near Cairo. Attackers killed and mutilated bodies of several of the officers.

The attack came after security forces descended onto two pro-Morsi protest camps in August 2013, killing hundreds.
