Beginning on 22 August, the Libyan National Army’s (LNA) Tariq Bin Ziyad Brigade (TBZ) clashed with members of the Qadhadhfa tribe in Qadr Abu Hadi, 20km south of Sirte. Some reports claim that clashes were prompted by an LNA security operation against drug trafficking. Other sources claim that they were related to the payment of salaries. The clashes evolved into a siege of Qasr Abu Hadi lasting more than five days, in which communications were suspended and all checkpoints surrounding the town were closed. On 26 August, the United Nations Support Mission in Libya (UNSMIL) issued a statement condemning the ‘disturbing reports’ from Qasr Abu Hadi pertaining to restrictions on freedom of movement, preventing civilians accessing hospitals, schools, shops and other basic facilities. Reports indicate that at least one LNA fighter and two Qadhadhfa combatants have been killed.
