An Egyptian court on Thursday has sentenced 27 persons to life in prison over joining the outlawed Muslim Brotherhood group and inciting violence, official news agency MENA reported.

Life sentence in Egypt means 25 years in jail.

The case dates back to 2016 when 37 Brotherhood members marched in the coastal city of Alexandria, carrying leaflets and chanting slogans instigating violence against state institutions.

The defendants were charged of protesting without license which violates the protest law, terrifying citizens and harming the public order.

Other 10 defendants were sentenced 10 years in jail over the same case, the report added.

Former Islamist President Mohamed Morsi was removed by the army in July 2013 in response to mass protests against his one-year rule.

Later security crackdown on his supporters left hundreds dead and thousands arrested.

Since Morsi's topple, detention and labelling his Brotherhood as terrorist, Egypt has been facing a wave of terror activities that left hundreds of policemen, soldiers and civilians dead.

A Sinai-based group affiliated with the Islamic State (IS) regional terrorist group claimed responsibility for most of the terror attacks in Egypt.
