Two people have been killed in clashes that broke out on Saturday, after a Cairo court cleared former President Hosni Mubarak of all charges of murder of protesters during the 2011 uprising of the Arab Spring.

A judge also sentenced the leader of Muslim Brotherhood and 25 others to three years in jail for insulting the court during the trial of 100 supporters on Sunday for charges of storming prisons during the uprising.

The punishment is being seen as unusual for misconduct in a courtroom, where Brotherhood supporters were shouting "void, void" during the judge's remarks, Reuters reported.

Violence broke out after Saturday's verdict, and one man was shot in Cairo, while at least nine were injured, Al-Arabiya reported.

Demonstrators collected at Cairo University and at the Abdel-Moneim Riad square calling for the 'fall of the regime', similar to the protests during the Arab Spring.

The court acquitted Mubarak who had been accused of conspiring to kill protesters in the 2011 revolution, during which 800 people were reportedly killed. The Cairo court also cleared Mubarak and his two sons of corruption charges relating to gas exports to Israel.

Mubarak, 86, had been given life sentence in 2012 for being complicit in the killing of demonstrators during the 2011 uprising that ultimately resulted in his falling from power.

However, an appeals court overturned the sentence last year citing technicality.
