Egypt's Court of Cassation has said Thursday it would rule 4 June on an appeal filed by the general prosecution against dropping charges against former president Hosni Mubarak over his alleged role in the killing of protesters during the 2011 uprising.

In November, a criminal court dropped charges against 86-year-old Mubarak over his complicity in the murder of protesters during the January 2011 uprising.

In the same case, Mubarak's former interior minister, Habib El-Adly, along with six of the latter's aides, were acquitted of murder and attempted murder related to the killing of protesters in 2011.

The prosecutor general started appeal procedures in December.

This leaves Mubarak only facing the final verdict in the retrial with his sons, Alaa and Gamal, in the presidential palaces case, set for 9 May.

They were originally convicted last May of embezzling LE125 million ($17.9 million), allocated for developing communications centres for the presidency, in order to develop their own private buildings.

Mubarak, who was ousted in a popular uprising in 2011, received a three-year prison sentence and his sons four-year sentences. Both Mubarak and his sons appealed against the court ruling.

Mubarak was previously cleared of other corruption-related charges.
