Ukrainian forces struck oil facilities in Russia and occupied Crimea, Ukrainian and Russian officials said, as part of Kyiv’s campaign to make Moscow pay an economic price for the full-scale invasion.

Ukraine’s General Staff said forces had struck Russia’s Krasnodar Krai region overnight, hitting the Grushovaya oil transshipment base near Novorossiysk.

The complex is one of the largest transshipment hubs in southern Russia for oil and petroleum products.

Russian regional authorities confirmed a Ukrainian drone sparked a fire at the facility, adding that there were no casualties.

While they did not comment on the extent of damage, they said 130 rescue workers were involved in putting out the blaze.
