On 4 May, ISIS claimed an attack against the Libyan National Army’s (LNA) 160 Brigade Jabril Baba training camp in Sebha, leaving eight LNA fighters dead. ISIS’ claim stated they killed or wounded at least 16 soldiers and freed inmates from the camp’s prison. A source at the prison confirmed ISIS stormed the jail without providing additional details. The head of the local municipality, Hamed al-Khaiyali, told journalists that one of the LNA fighters was beheaded and seven others shot or “slaughtered.” The LNA blamed ISIS and Chadian fighters for the assault.

On 25 April, the Government of National Accord (GNA) Ministry of Interior (MoI) arrested Yasser Saleh Khalifa al-Majri (aka al-Tajouri or Abu Dujaneh) for his alleged membership of Islamic State (ISIS). He allegedly joined the group in 2014. The MoI claimed he was planning to take advantage of the crisis in Tripoli to undertake an attack. It is unclear what the alleged target was. On 21 April, the MoI also arrested Abdussalam Shughib, because of his alleged connection to ISIS. Shughib was featured in a video threatening to attack the Special Deterrence Force (Rada) prison in Mitiga Airport.

On 25 April, ISIS fighters attacked the home of a LNA supporter, Khaloukh Massoud, in Ghadduwa and kidnapped him. ISIS executed Massoud in the desert and published photos of the incident.
