The Giza Criminal Court sentenced five defendants to 10 years of rigorous imprisonment in the case dubbed "Cabinet clashes" of 2011 on Saturday.
The court also ordered the defendants to pay EGP 17.6 million in compensation for vandalism. One of the defendants was sentenced to five years in prison.
The defendants are accused of weapons and drug possession, committing acts of vandalism by setting public and private property on fire and rioting outside the premises of state facilities.
Many people were killed and injured in the 2011 incidents.
In December 2011, security forces dispersed a three-week sit-in at the Cabinet building, which resulted in clashes in the area surrounding the Cabinet and Shura Council and led to the burning of the Scientific Institute.
Some 269 defendants are implicated in the case.
