The graft case against the 86-year-old Mubarak, who is kept in custody at a military hospital, is one of two against the former president who was ousted in a popular uprising in 2011 after nearly three decades in power. He is being retried over the killings of hundreds of protesters during the uprising.

Mubarak's two sons, one-time heir apparent Gamal and wealthy businessman Alaa, were also convicted Wednesday of graft and sentenced to four years in prison each in the same case.

The three Mubaraks were convicted of charges that they embezzled millions of dollars' worth of state funds in over a decade toward the end of Hosni Mubarak's rule. The funds were meant for renovating and maintaining presidential palaces but were instead spent on upgrading the family's private residences.

Hosni Mubarak ``had an obligation to restrain himself and his sons from stealing state funds ... but instead, he gave himself and his sons license to embezzle them,'' Judge Osama Shaheen said as he handed down the verdict.

The three Mubaraks were also fined 21.1 million Egyptian pounds ($2.9 million) and ordered to reimburse 125 million Egyptian pounds ($17.6 million) to the state treasury. They have the right to appeal their conviction before a higher court.

The Mubaraks had returned around 120 million Egyptian pounds to the state in connection with this case, but the proceedings against them continued.

Four other defendants in the case were acquitted.

Under Egyptian law, maximum sentences for embezzlement vary depending on the nature of the crime, but 15 years' imprisonment is not uncommon.
