An Egyptian military court has sentenced seventeen people to death for their involvement in bombing attacks on three churches and a police checkpoint in 2016 and 2017.
The deadly attacks killed more than eighty people, according to state news agency MENA.
Nineteen others were handed life prison terms for the attacks, which hit churches in Cairo, Alexandria and Tanta.
The sentences are subject to appeal.
Islamic State (IS) militants claimed responsibility for the Alexandria and Tanta bombings. The bombings, both of which were suicide attacks on Palm Sunday in April 2017, killed forty-five people.
IS also took responsibility for a December 2016 attack on a chapel adjoining St Mark’s, Cairo’s main cathedral, that left twenty-eight dead.
The cathedral is the seat of Coptic Pope Tawadros II and its security is normally tight.
