Turkey has not made a decision to close the Dardanelles and Bosphorus straits to Russian ships, a Turkish official with knowledge of the matter told Reuters on Saturday.
Earlier, Ukrainian President Volodymyr Zelenskiy thanked President Tayyip Erdogan for Turkey's humanitarian and military support, saying a "ban on the passage of (Russian) warships to the Black Sea" was very important for his country.
