Ten members of the Muslim Brotherhood have been sentenced to two years in jail and fined LE50,000 for taking part in an illegal protest in Marsa Matrouh, Al-Ahram Arabic news website reported.
The town, which is on the Mediterranean coast and has a high concentration of Islamists, witnessed heavy protests after the dispersal of sit-ins in support of ousted Islamist president Mohamed Morsi in August 2013.
A strict protest law was passed in November sanctioning the police to disperse demonstrations not pre-approved by authorities and impose heavy jail terms and fines.
Also on Monday, a Suez military court sentenced 17 Morsi supporters to up to ten years in jail for attacking army personnel and property in August 2013.
The Muslim Brotherhood – from which Morsi hails – was branded a terrorist group by Egypt's transitional government in December.
Dozens of Morsi supporters have been given similar sentences during the past months.
