Turkey’s President Recep Tayyip Erdogan urged Russia and Ukraine to stop targeting civilian ships in the Black Sea and agreed with Ukrainian President Volodymyr Zelensky to work on a new grain corridor through the sea, according to Al Jazeera.

The two spoke at a joint news conference in Istanbul on Saturday. “It is clear that attacks against civilian vessels and actions that further escalate tensions in the Black Sea serve no one’s interests,” Erdogan said. He added that the attacks are unacceptable “regardless of who carries them out or what justification is offered.”
