Derna in eastern Libya has been the scene for fierce clashes since Sunday between Derna Protection Force and the self-styled army forces led by Khalifa Haftar.

Eyewitnesses said clashes renewed in Wasit Al-Blad neighborhood, where Derna Protection Force fighters are still in control as Haftar's forces continue to encircle them.

They also said artillery shells were heard all over the city.

Meanwhile, Brigade 303 of Haftar's forces said it was targeting "terrorists" in the neighborhood, saying fighting grew intense since Monday morning as it advanced to end the presence of Derna Protection Force.

Pro-Haftar social media pages posted footage showing tanks shelling Wasit Al-Blad neighborhood (Old Town) while some said that houses of displaced families were robbed by Haftar-Loyal forces.

Videos posted in the past days showed the destruction in Derna due to artillery shelling by Haftar's forces.

Haftar's forces announced last May a military operation to "Liberate Derna" from Derna Protection Force, which drove ISIS out three years ago, and then they declared victory in July, despite recurrent fighting and continued displacement ever since.
