On August 6, Ukrainian forces crossed from the Sumy region into Russia and swiftly seized a significant part of the Sudzhansky district in the Kursk Oblast.
Over the ensuing weeks, Ukraine made a number of substantial and headline-grabbing gains in this Russian region, with even Moscow admitting that Kyiv had captured scores of settlements and occupied hundreds of square kilometers of territory.
In making the largest incursion onto Russian soil since World War II, Kyiv says its aims include pushing back Russian artillery, disrupting supply lines, and diverting forces from the frontline in Ukraine’s eastern Donetsk region, where Moscow has been making grinding gains in recent months.
Meanwhile, Russian forces have reportedly begun attacking Ukrainian troops in the Kursk region and have retaken some territory.
