Turkish President Tayyip Erdogan urged Ukrainian counterpart Volodymyr Zelenskiy to help stop attacks by Russia and Ukraine on commercial vessels in the Black Sea. Turkey, a NATO member that has maintained ties with both Moscow and Kyiv since Russia's full-scale invasion in 2022, says it has offered proposals to both sides and is awaiting a response. Ankara also supports a maritime truce and the safe movement of grain, while Turkey and the United Nations previously helped establish the Black Sea Grain Initiative in July 2022. Russia withdrew from that agreement the following year, citing obstacles to its food and fertiliser exports.
