15 people were on Thursday sentenced to 10 years in prison by an Egyptian court for inciting violence and assaulting security forces in 2013 in the southern province of Minya.
The 15 are said to be supporters of the outlawed Muslim brotherhood affiliated to former president Mohamed Morsi.
Morsi was ousted by in a military takeover in early 2013 following mass protests against his one-year rule.
The prosecution also charged the 15 with joining a banned group and calling for protests in response to Morsi’s ouster and the later security crackdown on his loyalists.
Only one was in custody while the rest were sentenced in absentia.
Following his ouster, supporters of Morsi attacked many security officers and churches of the Coptic minority in several provinces nationwide.
The violence led to the arrest of thousands of Egyptians.
Last week, 26 defendants were similarly sentenced up to 10 years in prison over committing violence and sabotage and storming a police station in January 2014.
Earlier this week, an Egyptian court ordered the execution of 15 jihadist militants convicted of carrying out a deadly attack on an army outpost in the Sinai Peninsula in 2013.
