Clashes between armed groups left southern Libyan city, Sabha, in tumultuous conditions over the last two days.

Tubu tribe's force loyal to Khalifa Haftar - who leads a self-proclaimed army in east Libya - attacked Friday the positions of Brigade 6 of Presidential Council's (PC) Defense Ministry, sources from Sabha municipality reported.

Sabha Medical Center confirmed that no injuries arrived at its sections from the clashes, despite the fact that eyewitnesses reported the clashes as very intense.

Sources from Sabha also said that the Brigade 6 fighters foiled the attack, which came from three axes, adding that another attack is being planned currently by the Haftar-loyal fighters.

"It is all about a decision issued by Haftar last week to join the Brigade 6 to his forces, which was rejected by the brigade saying it is loyal to the Defense Ministry of the PC." The sources added, saying more blood could be shed as several Chadian fighters arrived at the agriculture crossroad in Sabha to join the attack.

Brigade 6 commander Ahmed Al-Etaibi said in a televised statement Friday that they are part of the PC's Defense Ministry and denied the claims of Haftar and his forces.

"The militias who attacked our locations wanted to take control of it and then seize the entire southern region because the fall of the brigade means the fall of the security of the south." He explained.
