The bodies of 21 Egyptian Coptic Christians who were murdered in 2015 by Islamic State (IS) militants, were discovered in Libya’s coastal city of Sirte, officials said.

The bodies were found on the outskirts of the coastal city with their hands cuffed behind their backs, dressed in the same orange jumpsuits they were wearing in a video that showed their beheading, the Libyan attorney general’s office announced on Friday night.

It added that victims’ heads were found nearby, and DNA tests would be carried out in order to identify the bodies, reports Efe news.

The discovery comes a week after Attorney General Sadiq al Sour, announced that government troops had captured one of the militants who had filmed the execution.
