MOSCOW (Reuters) -Russia’s Black Sea port of Tuapse has suspended fuel exports, while the local oil refinery halted processing crude following November 2 Ukrainian drone attacks on its infrastructure, according to two industry sources and LSEG ship tracking data.

Ukraine said on Sunday its drones struck Tuapse, one of Russia’s main Black Sea oil ports, causing a fire and damaging at least one ship, as part of Kyiv’s efforts to undermine Russia’s war economy by targeting its energy infrastructure.

The regional administration confirmed the strike sparked a fire at the port.

Ukraine has for several months been striking Russian oil refineries, depots and pipelines, while Ukrainian energy infrastructure has also been the target of Russian strikes in a war that is approaching its fourth year.
