CAIRO (Reuters) - Egypt's public prosecutor appealed on Tuesday against a court decision last Friday to drop charges against former president Hosni Mubarak, his interior minister and six aides over the killing of protesters in the 2011 uprising, citing flaws in the ruling.

"A study of the reasons for the ruling revealed legal flaws that tinged the judgment," the prosecutor said in a statement.

Such an appeal is an integral part of the legal process in Egypt and was expected to be lodged following the verdict. If Mubarak is retried in the case, it would be for the third and final time under Egyptian law.
