Ukrainian President Volodymyr Zelensky marked the 500th day of the war Saturday by hailing the country’s soldiers in a video from a Black Sea island that became the symbol of Ukraine’s resilience in the face of the Russian invasion.

Speaking from Snake Island, Zelensky honored the Ukrainian soldiers who fought for the island and all other defenders of the country, saying that reclaiming control of the island “is a great proof that Ukraine will regain every bit of its territory.”
