Speaking to Reuters, Libya's Prime Minister Abdul-Hamid Dbeibah said on Friday he was unaware of any understanding between Russia and Turkey on a withdrawal of their foreign fighters, adding that such a move would be welcomed.

Dbeibah said he had not heard of this agreement regarding the withdrawal of fighters, adding that his government would welcome any agreement and the exit of any forces, fighters or mercenaries with any support from any party, reiterating that they had been talking with all parties regarding the withdrawal of foreign forces from Libya.

Reuters said that following a UN-backed conference in Berlin last month, German and US officials said Turkey and Russia, which back opposing sides in Libya, reached an initial understanding on a step-by-step withdrawal of their foreign fighters.

Dbeibah also said he was committed to holding elections on December 24, but warned that some lawmakers may be reluctant to give up power, reiterating that he has not yet decided whether to run for office - an action he signed not to do with the Libyan Political Dialogue Forum's roadmap before the interim executive authority was elected.

Dbeibah told Reuters it would be very difficult to unify Libya's military, adding that he was communicating with Haftar, describing Haftar as "a difficult military person," but said "we communicate with him but things are not easy."

UN special envoy for Libya, Jan Kubis, said on Thursday at the Security Council session on Libya that that Haftar's forces have not allowed Dbeibah's unity government to take control of the area they command.
