Ukrainian drones attacked energy facilities in Russia's Astrakhan and Volgograd oblasts overnight on Feb. 3, causing fires, according to local authorities. The news comes as Ukraine ramps up long-range strikes against Russian energy infrastructure to stifle Moscow's gas and oil exports that fuel its war chest.

Units of the Ukrainian Armed Forces' Unmanned Systems Forces (USF), together with Defence Intelligence of Ukraine and other components of Ukraine’s defence forces, launched an attack on the LUKOIL-Volgogradneftepererabotka refinery in Russia's Volgograd Oblast on the night of 30-31 January.

The wreckage of a downed drone fell on the refinery, causing a fire that was quickly extinguished, Governor Andrey Bocharov said.
