An Egyptian court has upheld a one-year prison sentence against former prime minister Hisham Kandil, who was appointed by deposed president Mohammed Mursi.
Kandil was handed the sentence in April, when he still headed the government, for failing to implement a court ruling to renationalise a textile company sold off by the Hosni Mubarak administration.
Judge Khaled Hassan said the prison sentence must now be carried out.
Elsewhere in Egypt, gunmen killed three policemen in the Sinai Peninsula, security sources said.
Gunmen killed two policemen as they were eating breakfast outside a police station in the city of El-Arish in North Sinai.
In a separate attack, a police officer died after being shot in the head and chest as he walked in the city.
Gunmen also killed a civilian in the nearby town of Sheikh Zuwaid.
Meanwhile, an Islamist militant group released a video of an earlier drive-by shooting of an army colonel.
Security sources confirmed that gunmen had killed the colonel, identified as Mohamed al-Komi, on 14 August on a desert highway near the Suez Canal city of Ismailia
