ISTANBUL (AP) — Ukrainian President Volodymyr Zelenskyy was in Istanbul on Friday for talks with Turkish President Recep Tayyip Erdogan, whose NATO-member country has sought to balance its close relations with both Kyiv and Moscow and repeatedly offered to act as a peace broker between them. During the talks in Istanbul, Erdogan was expected to press for negotiations to end Russia's war in Ukraine, now in its third year, a Turkish government official said. Talks would also focus on a possible new measure that would guarantee navigational safety of commercial vessels in the Black Sea, the official said.
