Several hundred protesters gathered at a road leading into Tahrir Square in Cairo to demonstrate against Saturday's court verdict that dropped charges against former president Hosni Mubarak of killing protesters during the 2011 revolution.
A group of around 1000 people gathered in front of the army vehicles and barbed wire that is blocking off the entrance to the iconic square, while a smaller group of around 50 people gathered a few metres away at the Egyptian Museum, according to an Ahram reporter at the scene.
Army and police forces had blocked off the square after the verdict and prevented attempts by the protesters to enter.
Protesters carried pictures of some of those who were killed during the January uprising. Demonstrators also chanted against both the government and the Muslim Brotherhood.
They demanded the execution of the former autocrat.
Earlier on Saturday, Cairo Criminal Court acquitted former president Hosni Mubarak, the former interior minister and top security chiefs of charges of killing protesters during the 2011 uprising. Mubarak, his two sons Alaa and Gamal, and businessman Hussein Salem were also acquitted of corruption charges related to the export of natural gas to Israel at below-market prices.
In Alexandria, four protesters were briefly detained at a protest against the verdict. Security forces dispersed the demonstration of dozens shortly after it started.
Dozens have also gathered in Revolution Square in Mansoura city in the Delta where protesters chanted against "military rule" and demanded justice, according to Ahram Arabic news website.
