The recent progression in the conflict in Ukraine has seen Russian forces take control of Siversk, a town in the Donetsk region. This event marks a significant development as Siversk is the last remaining Ukrainian-held city within what is referred to as the ’fortress belt’ in eastern Ukraine. The loss of Siversk indicates a strategic advancement for Russian military operations in the area and potentially alters the local military dynamics. The situation remains fluid, with ongoing military engagements and geopolitical implications continuing to unfold.
