Today's verdict sentenced another 12 to life in prison and another six to 15 years. Two have been acquitted, and two were convicted in absentia.
Military prosecutors had accused the defendants of belonging to an illegal group and plotting to assassinate police and army personnel. The verdict can still be appealed. The official spoke on condition of anonymity because he wasn't allowed to brief reporters.
Earlier this month, an Egyptian court recommended the death sentence against six people.
