CAIRO : An Egyptian court Sunday sentenced 101 supporters of ousted Islamist president Mohamed Morsi to three years in jail for acts of violence in the Nile Delta city of Damietta, state media reported.

Egyptian courts have sparked international concern over a spate of mass trials of Morsi’s supporters, with rights groups repeatedly accusing the authorities of using the judiciary as a tool of repression. State news agency MENA said the 101 Morsi supporters were jailed for three years after they were found guilty over July 2013 clashes in which 18 people were injured in Damietta, while 17 co-defendants, all minors, were acquitted.

Since Morsi’s ouster in July last year, a government crackdown on his supporters has killed 1,400 people in street clashes, and over 15,000 Islamists and protesters have been jailed. At least 200 people have also been sentenced to death in speedy mass trials, including Mohamed Badie, leader of Morsi’s Muslim Brotherhood movement.

 Morsi himself is currently on trial in three separate cases, with a fourth yet to come to court.
