Turkish minister of foreign affairs Mevlüt Çavuşoğlu said on Monday evening that Turkey warned “all countries, that have coast to Black Sea, or not, not to let warships pass through the straits” according to Turkey’s state-run news agency Anadolu.
On Sunday, Çavuşoğlu said Turkey recognizes Russia’s invasion as “war” which gives Turkey certain control over the straits that connect the Black Sea, Marmara and Aegean.
"We warned all countries, that have a coast on the Black Sea or not, not to let warships go through the straits," Çavuşoğlu told reporters after a Cabinet meeting in Ankara, Anadolu reported.
"To date, there has been no request for passage through the straits [since the war started],” Çavuşoğlu said according to Anadolu. “Until today, the Russians were asking whether we would implement Montreux if needed. We told them that we would apply it word by word,” he added.
"If Turkey is not a party to the war, it has the authority not to allow the passage of the belligerent countries' ships through the straits. If the warship is returning to its base in the Black Sea, the passage is not blocked,” he explained.
More background on Montreux: The 1936 Montreux Convention gives Turkey the authority to ban warships of all countries, regardless of they are party to war or not and regardless they have a coast on the Black Sea or not, to pass from the straits during times of war if Turkey is a party of the war or if Turkey says it is under threat.
