In September 2018, new clashes occurred in Tripoli between pro-GNA forces and the 7th Brigade militia from Tarhuna.[99][100] The warring parties signed a ceasefire to end the clashes on 25 September.[101] Clashes erupted again briefly on November 14, 2018 between 7th Brigade and Abu Saleem Central Security Force, but ended after a ceasefire. Sources close to Khalifa al-Ghwail said the clashes occurred due to the Palermo Conference lacking any resolutions to expel pro-Sarraj militias from Tripoli.[102]
