The former official of North African affairs at the US State Department, William Lawrence has said that the Russian interference in Libya is a matter of concern to the majority of the EU countries including NATO member states, and not just to the US.

Speaking to Al Jazeera, Lawrence said that the US message to Khalifa Haftar to retreat from his attack on Tripoli is a very important step.

Regarding the memorandum of cooperation signed between Libya and Turkey, the US official said Washington has no trouble in assisting the Government of National Accord.

"The US does not wish to see an escalation of arms race in Libya, therefore, it is making the utmost to attain a political solution," the US official explained.
