Russia striking Sumy Oblast due to Kyiv's successes in Kursk incursion, Ukraine's military says.

The Russian military is striking Sumy Oblast because of Ukraine's successes in Russia's Kursk Oblast, Vadym Mysnyk, a spokesperson for the Ukrainian military's Operational Tactical Group Siversk, told Radio Free Europe/Radio Liberty (RFE/RL) on Sept.

Mysnyk nevertheless said that Russian strikes on Sumy Oblast would have continued even if Ukraine had not successfully advanced in the Kursk sector. While Russia has ramped up attacks against the region since August, Sumy Oblast has been shelled on a daily basis since the beginning of the full-scale invasion in 2022.

This may indicate that Russia's resources are "not unlimited," he added. Russia recently launched a counterattack in Kursk Oblast, seeking to dislodge Ukrainian troops from its soil.

President Volodymyr Zelensky said that "everything was going according to our plan" and that the Russian "rapid" offensive had not yet achieved "serious" success in the area.

Russia launches counteroffensive in Kursk - can it push Ukraine off its own turf? More than a month after Ukraine launched an unprecedented incursion into Russian territory, Russian forces have begun counterattacking in Kursk Oblast, aiming to eventually drive Ukrainian troops out of the partially occupied border region.
