During a pool training session months ago, Ukrainian war veteran Oleh Tserkovnyi was struck by an idea: What if a group of veterans swam across the strait of Bosphorus, between Turkey’s European and Asian shores, for charity? After months of rigorous training he and two others joined more than 2,800 swimmers on Sunday in the 6.5-kilometer (4-mile) race.
