Turkish Foreign Minister Hakan Fidan met with Russian President Vladimir Putin in Moscow on Monday to discuss efforts to end the war in Ukraine and follow up on recent talks held in Istanbul, a Turkish Foreign Ministry source said.

Fidan also met with Russia's chief negotiator and will see Foreign Minister Sergei Lavrov on Tuesday. While there is no definite date for further discussions, Turkey has offered to host and mediate, according to Reuters.

The Istanbul meeting earlier this month resulted in a prisoner exchange and formal cease-fire pledges, but no agreement was reached. Putin and Fidan also talked about bilateral economic and energy connections.

Fidan is expected to visit Ukraine later this week. Russia has identified Turkey and several Gulf States as possible venues for future negotiations, Reuters reported.
