Egypt's public prosecutor general's office has said it will appeal a court ruling that dropped a murder charge against ex-president Hosni Mubarak over the deaths of protesters during the country's 2011 uprising.

"The prosecutor general has decided to appeal," it said in a statement on Tuesday, after a Cairo court on Saturday ordered the dropping of murder and corruption charges against Mubarak, who ruled for three decades until being driven from office.

"The ruling was marred by a legal flaw," the prosecutor's office said, adding that its decision to appeal was "not influenced by disputes among political groups".

Mubarak is serving a three-year sentence in a separate corruption case.

Seven of Mubarak's security commanders, including feared ex-interior minister Habib al-Adly, were acquitted on Saturday over the deaths of roughly 800 protesters during the 2011 revolt.

Corruption charges against Mubarak's sons Alaa and Gamal were also dropped.

The Court of Cassation, the country's highest court, can now either confirm Saturday's ruling or decide to cancel it, in which case it would consider the case itself.

An appeals court had previously overturned an initial life sentence for Mubarak in 2012 on a technicality, ordering the retrial that saw the charges dropped on Saturday.

His lawyer has said the 86-year-old could now see an early release from the military hospital where he is being held, as he has already served two-thirds of his sentence when time held in preliminary detention since his arrest in 2011 is taken into account.

Angered protesters

After Saturday's verdict, more than 1,000 protesters gathered at an entrance to Cairo's Tahrir Square - the epicenter of the anti-Mubarak revolt - chanting slogans against the government of President Abdel Fattah al-Sisi.

Resulting clashes left two people dead and several wounded.

The court's ruling has come under fire from Mubarak opponents, critics and some leftist leaders, and sparked accusations that the authorities are interfering with the courts.

The government has denied any involvement in court rulings and on Sunday Sisi ordered a review of the criminal code to prevent any legal irregularities.

In his first comment on the verdict, Sisi, who was Mubarak's intelligence chief, said Egypt was charting a new course.

"The new Egypt... is on a path to establish a modern democratic state based on justice, freedom, equality and a renunciation of corruption," he said.
