Turkish officials assured that the passage through the Turkish Straits to the Black Sea was continuing amid spillover of the Russia-Ukraine war into the latter.

On Saturday, Bloomberg ​News reported ⁠that Ankara had restricted commercial ship traffic entering the Black Sea following attacks on vessels there, including Turkish-owned ships. Türkiye has issued repeated warnings to Moscow and Kyiv over the attacks in the Black Sea, urging the warring sides to take measures to ensure navigational safety in the area. On Saturday, Foreign Minister Hakan Fidan said Ankara had conveyed ⁠to ⁠Moscow and Kyiv that they should declare a moratorium on their attacks in the Black Sea.

Two Turkish government officials, who spoke to Reuters on condition of anonymity, said Türkiye had implemented some temporary measures because it had been highly uncomfortable about security for some time, but that passage was clear under the conditions ⁠of the Montreux Convention. They did not give further detail.

The 1936 Montreux Convention of the Regime of the Straits gives Türkiye ​control over the Bosporus and Dardanelles, and the power to ​regulate transit of naval warships. It also guarantees the free passage of civilian vessels ⁠in peacetime and ‌restricts the passage of ships not ⁠belonging to Black Sea countries. Türkiye, ‌which has NATO's second-largest army, has maintained cordial ties with ​both Kyiv and Moscow ⁠since the Russia-Ukraine conflict erupted in 2022. It has refused to join Western sanctions ⁠on Russia, ​while providing military support, including from its own inventory, to Ukraine.
