Ukraine’s Defense Minister Mykhailo Fedorov said Ukrainian strikes on Russian targets in temporarily occupied Crimea and southern areas have already caused major logistical problems for Russian troops.

Speaking at a joint press conference in Kyiv with Sweden’s defense minister Pål Jonson, Fedorov said that in the south there are sectors of the front where Russian infantry—because of destroyed or disrupted logistics—must walk roughly 30 km on foot to get to their positions.

He linked the difficulties not only to getting troops to the line but also to supplying them and providing fuel for generator equipment used by unmanned aerial vehicle operators. Fedorov said these issues create an “accumulation of crises,” including problems connected to critical infrastructure and fuel availability in Crimea.

As an example, he said Russian authorities first announced fuel sales via QR codes in Crimea, later cancelled it, and then made it impossible to buy fuel at all—using this to illustrate how multiple disruptions are compounding.

Fedorov said Ukraine’s operation to influence Russia is ongoing and that intensifying strikes and allocating more resources remains part of the plan, arguing that the net effect is reduced Russian combat effectiveness and disrupted troop maneuverability.
