Cairo Criminal Court sentenced Saturday a defendant in the "Zeitoun terrorist cell" case to three years in prison following an appeal.
The court also placed now convicted Ammar Abdel-Ellah under police surveillance for three years.
Abdel-Allah was convicted of forming a terrorist organisation called the "Regiment of Loyalty and Disavowal" (Sareyet Al-Walaa wa Al-Bara’) that aimed to target Copts and foreigners in Egypt, as well as surveying Egypt's oil pipelines and ship movements in the Suez Canal in order to plan attacks on ships.
Last year, in June 2016, Egypt's Supreme State Security handed prison terms of seven to 10 yeas to defendants in the case, while acquitting others.
Saturday’s verdict is one made following a series of appeals by some of the defendants.
The case dates back to 2007, when 25 people, adopting armed jihadist ideologies, committed an armed robbery at a jeweller's shop in Cairo's district of Zeitoun.
Four Copts were killed and two others injured during the robbery.
