Egyptian authorities executed 15 people on Tuesday who had been convicted in a terrorism-related case dating back to 2013, Khaled Al-Masry, a defence lawyer in the case said.

The 15 men were convicted of the murder of military personnel during a militant attack in Arish, North Sinai, on 15 August 2013. The assault on a checkpoint left one army officer and eight soldiers dead.

A military court issued a preliminary death sentence against the defendants in 2015.

In November of this year, the High Military Cassation Court rejected an appeal against the sentence, and the 15 men were issued with final verdicts.
