Zelenskyy visits troops on Ukraine’s southern front

Ukrainian President Volodymyr Zelenskyy has visited troops on the southern front line.  While his army battles a Russian onslaught in the Donbas region, Ukrainian forces have also been fighting off attempts by Russia to seize more territory near the southern cities of Mykolaiv and Odesa.  However, with little change to front-line positions in recent days, the head of NATO, Jens Stoltenberg, says the war could go on for years.
