ANKARA, Aug 4 (Reuters) - Turkey on Tuesday called on Russia and Ukraine to take measures to ensure navigational safety in the Black Sea after a drone attack hit a Turkish-owned vessel and seriously injured three crew members near Russia's Novorossiysk port.
The Turkish Foreign Ministry said Ankara was seriously concerned about the targeting of civilians vessels in the Black Sea despite "all of our warnings", adding it was closely following the condition of its citizens.
