An Egyptian court has sentenced 78 minors to between two and five years imprisonment for participating in protests calling for the return of the ousted president and leader of Muslim Brotherhood Mohamed Morsi, according to judicial sources.

"The 78 minors, members of the Muslim Brotherhood, were arrested for participating in protests organised by the group calling for the downfall of the regime in which they blocked roads and transportation, and terrified citizens," state agency MENA reported.

The boys were aged between 13 and 17 years old and they were sentenced at a court in the city of Alexandria.

Egyptian president Abdel Fattah al-Sisi has continued his crackdown on supporters of Morsi following the coup he led last year and has designated the Muslim Brotherhood as a terrorist organisation, forcing them out of the political fold in the country.

Al-Sisi won 96.9% of the vote in May's presidential election against sole competitor Hamdeen Sabahi.

Morsi faces of series of charges levelled against him by Sisi's administration and has denounced his trial at the hands of an Egyptian court which he has called illegitimate.
