This is reported by Aljazeera. Judging by the video posted on the Internet, the senior leader of the armed forces of Haftar Mahmoudal-Verfali reads the charges to the militants, and then executes the execution.
Most likely the video was filmed on July 17. And on July 18, the UN called on the Libyan National Army (LNA) Haftar to investigate the execution of prisoners. (LNA) Haftaar directs the eastern part of Libya. The report of the execution began to come from the moment when the leaders of the Libyan rival factions announced a meeting in Paris this Tuesday. The meeting is scheduled to end the political crisis in the country.
Recall, as reported URA-Inform, IGIL called on its supporters to attack the US, Europe and Russia.
