The International Criminal Court (ICC) has, for the first time, issued an arrest warrant based solely on social-media-sourced evidence in a case involving a Libyan military commander.

The warrant, issued on the 15 August, accuses Mahmoud al-Werfalli of mass executions and summary killings. Werfalli served in the Al-Saiqa Brigade, an elite force of military strongman Khalifa Haftar’s so-called Libyan National Army (LNA).

Werfalli has been accused by the ICC of directing or participating in a series of executions of 33 prisoners between June 2016 and July 2017 in Benghazi and the surrounding areas.

The charge, murder as a war crime under Article 8(2)(c)(i) of the Rome Statute, is based on seven separate incidents of execution which were documented in seven separate pieces of video footage.
