Russia on Friday said it was very concerned by Turkey potentially sending troops to Libya and that a security deal between the two nations raised many questions, the Interfax news agency cited a source at Russia's foreign ministry.

Libya's Government of National Accord (GNA) in Tripoli said on Thursday it had ratified a security and military cooperation deal with Turkey, in an effort to end a months-long offensive by the eastern-based National Libyan Army (LNA), which is led by Commander Khalifa Haftar.
