A search operation is underway in Istanbul for a Russian swimmer who disappeared during the annual cross-Bosphorus race on Sunday, according to state-run media.
Turkish coast guard and maritime police vessels were deployed on Monday to locate Nikolai Svechnikov, identified by the Anadolu news agency. Mr Svechnikov failed to complete the challenging 6.5-kilometre (4-mile) event, which spans from Istanbul’s Asian shore to its European side.
