The commander of the frontlines at Al-Saiqa Force of the self-styled army in eastern Libya, Mahmoud Al-Werfalli, has escaped his detention in Rajma, where Khalifa Haftar's general command is located, sources from the eastern region reported Wednesday.

The mysterious and quite cinematic prison break of the man, who is wanted by the International Criminal Court (ICC) for war crimes and crimes against humanity, left some skeptical that he might have been released by Haftar at the pressure of Al-Werfalli's loyalists.

According to the sources, Al-Werfalli arrived in Benghazi heavily escorted by his loyalists, who are mostly from the special forces' personnel, amid gunshots in the air to celebrate his comeback.

Al-Werfalli has been featuring in many execution IS-styled videos lately clearly showing himself in action, killing captives at point blank range.

The ICC issued two arrest warrants of him, one in August 2017 and one in April 2018 for crimes against humanity, over 30 extrajudicial killing incidents and war crimes.

Al-Werfalli turned himself in to the Al-Marij town Public Prosecutor in February for investigations of war crimes and there was then a wave of riots in Benghazi streets in demand of his release.
