Russian Foreign Minister Sergei Lavrov and Defence Minister Sergei Shoigu will visit Turkey on Sunday for talks, the two countries' foreign ministries said on Saturday, with media reports saying discussions would focus on Libya.
Turkey supports Fayez al Serraj's internationally recognised Government of National Accord (GNA), whose forces have in recent weeks repelled a 14-month assault on Tripoli by Khalifa Haftar's Libyan National Army (LNA).
Russia, along with the United Arab Emirates and Egypt, backs the LNA. The United Nations said on Wednesday that Libya's warring sides had begun to engage in a new round of ceasefire talks.
"During the visit, delegations are expected to have consultations and discuss coordination on regional issues," the Turkish Foreign Ministry said of the visit by the Russian delegation, which will include military and security officials.
Turkish state broadcaster TRT Haber said the ministers would also discuss the situation in Syria.
Russia backs the Bashar al-Assad regime in war-torn Syria, while Turkey supports the opposition forces. A Turkish-Russian deal three months ago produced a ceasefire that halted fighting in northwest Syria's Idlib, but airstrikes hit the region this week.
