Ukraine presses on with counteroffensive despite Russian resistance.

Russian President Vladimir Putin has dismissed Ukraine's counteroffensive, saying it has "no chance" of success. He made the comments at the St. Petersburg Economic Forum, where he also talked up Russia's financial health. Meanwhile, Ukrainian President Volodymyr Zelenskyy said reports from the front lines were "generally positive, but it's very difficult." US officials have warned that the war will be a "marathon, not a sprint," and a poll suggests 45% of Russians believe the conflict will last at least another year.
