TRIPOLI, June 6 (Xinhua) -- Libyan Prime Minister Abdul-Hamed Dbeibah on Friday ordered an investigation into clashes that broke out Thursday in the northwestern coastal city of Sabratha.

The Information Office of the Prime Minister said in a statement that Dbeibah had instructed the commander of the Western Military Zone "to start an immediate and thorough investigation" into the clashes.

"The instructions are part of orders made yesterday to assign the Western Military Zone commander to urgently interfere on ground and stop the fighting," the statement added.

According to local media, clashes broke out on Thursday between rival armed groups in Sabratha, some 70 km west of the capital Tripoli, and lasted until Friday morning. No casualties have been reported so far.

Since the fall of the late leader Muammar Gaddafi's regime in 2011, Libya has struggled with insecurity and political instability. ■
