Long-range sanctions reach moscow region, oil refineries keep burning: results of deep-strike operations in May

Throughout May 2026, the geographic scope of Ukrainian deep-strike operations extended to more than ten regions of the russian federation, including Moscow, Vladimir, Kirov, and Samara oblasts. The longest-range strike reached 1,700 kilometers from the state border.

As the President of Ukraine has emphasized, Ukraine’s response to russia’s prolongation of the war and its attacks on Ukrainian cities and communities is fully justified. Ukraine is sending a clear message to russians: the aggressor must end the war.

Long-range strikes against russia were intended, in part, to deprive the enemy of the economic capacity to continue its aggression. Deep-strike operations also strengthen Ukraine’s path toward ending the war from a position of strength.

The Ministry of Defence of Ukraine presents an overview of russia’s losses resulting from Ukrainian long-range strikes in May.
