On 18 March, Libyan National Army (LNA) spokesman Ahmed al-Mismari said the LNA had found a mass grave of jihadist fighters in Ganfuda, Benghazi. The grave contained the corpse of former Benghazi Revolutionaries Shura Council (BRSC) leader Jamal Makhzoum as well as the corpses of Ansar al-Sharia commanders. The BRSC has confirmed Makhzoum was killed in Ganfuda.

A video was widely shared on social media appearing to show the decomposing body of Makhzoum strapped to the front of a vehicle then being paraded around by LNA fighters. Other photographs show the corpses of jihadist fighters, which also appear to have been exhumed, with LNA fighters posing and taking selfies with the bodies. Another vide which has been circulated shows footage of a man, allegedly identified as Colonel Mahmoud Warfali, executing three kneeling prisoners

The exhumation was condemned by the Libyan Nation Commission for Human Rights (LNCHR) as a ‘heinous’ war crime. On 20 March, UN envoy to Libya Martin Kobler and the UK ambassador to Libya Peter Millet both condemned the mutilation of corpses and urged all parties to respect international law. On 20 March, Mismari said that cases of abuse and murder of prisoners were being referred to the military police under the LNA.
