Egypt's top appeals court upheld on Tuesday death sentences against 13 members of the terrorist group Ajnad Misr, who were convicted on charges including murder.
The defendants were first handed the death penalty by a lower criminal court in December 2017 before they later appealed the sentences.
They were convicted on the murder of security personnel, attempted murder, joining an outlawed group, and possessing firearms, in association with events that took place between 2013 and mid-2015.
Tuesday's rulings by the Court of Cassation, the country's highest court, are final and cannot be appealed.
Ajnad Misr, or Soldiers of Egypt, emerged in early 2014 and claimed responsibility for a number of attacks on security forces, mainly in the Egyptian capital. The group was designated a terrorist organisation by the Egyptian government in the same year.
Its leader was killed by security forces in 2015, and many of its members are in jail.
The court also upheld life sentences for 17 defendants, 15-year prison terms for two others and five-year terms for seven.
