What was Ukraine's response to claims of a major Russian military operation in the Sumy region?

Kyiv firmly rejected claims of a major Russian military operation in the Sumy region, stating that Ukrainian forces had successfully destroyed what was only a small sabotage group rather than a significant offensive. This response highlights Ukraine's efforts to counter Russian narratives about military advances. The Sumy region holds strategic importance, having been previously targeted during Russia's initial February 2022 offensive, though Russian forces withdrew from the area approximately six weeks later. Ukraine's denial appears aimed at preventing panic and maintaining confidence in their territorial control along this sensitive border area.
