Ukrainian forces reclaim 50 square kilometers in "Vivaldi" counteroffensive
Ukraine's counteroffensive operation, which has recovered 50 square kilometers of territory, is being described as one of Ukraine's most important victories of 2026. The news coincided with a Ukrainian long-range strike on a major Moscow oil refinery during Russia's State Duma elections.
On day 1670 of the Russo-Ukrainian war, new gains by Ukrainian armed forces along the front line have been reported. An operation codenamed "Vivaldi" has resulted in Ukrainian forces reclaiming 50 square kilometers of territory previously under Russian control.
The counteroffensive is being described as one of Ukraine's most important victories of 2026, underscoring its significance within the broader context of a war in which both sides have spent years fighting over territorial control.
Strike on oil refinery
Alongside the territorial gains on the ground, Ukrainian forces carried out a long-range strike that reached a major oil refinery in the Moscow region. Such strikes on Russian oil infrastructure form part of Ukraine's strategy to weaken Russia's economic and military capacity, targeting facilities that supply fuel to the Russian armed forces and the broader economy.
Notably, the strike on the Moscow-area refinery occurred during the exact period when Russia's State Duma elections were taking place. This timing has drawn additional attention to the event, both in the context of Russian domestic politics and on the international stage.
Taken together, the two developments — territorial recovery on the front line and the successful long-range strike — are being presented as evidence of Ukraine's ability to achieve simultaneous results both on the ground and deep inside Russian territory. The war between Russia and Ukraine has continued since February 2022, with both sides regularly reporting on their operations and outcomes, which are often assessed differently depending on the source.
