Peter Greste and Mohamed Fahmy were sentenced to seven years, and Baher Mohamed sentenced to 10, Al Jazeera reported.
Mohamed was sentenced to an additional three years for possession of ammunition. Mohamed was in posession of a bullet casing he had found on the ground during a protest.
Other Al Jazeera journalists being tried in absentia were sentenced to 10 years. Their names are: Alaa Bayoumi, Anas Abdel-Wahab Khalawi Hasan, Khaleel Aly Khaleel Bahnasy, Mohamed Fawzi, Dominic Kane and Sue Turton.
Al Jazeera rejected the charges against its journalists and maintains their innocence.
Greste, Fahmy and Mohamed were arrested in December in Cairo as they covered the aftermath of the army’s removal of Mohamed Morsi from the presidency in July. They were accused of producing false news reports of the situation in Egypt.
The prosecution produced a number of items as evidence including a BBC podcast, a news report made while none of the accused were in Egypt, a pop video by the Australian singer, Gotye, and several recordings on non-Egyptian issues.
