More details have emerged about a reported Ukrainian drone strike in Russia's southern Krasnodar region last night
In a post on Telegram, regional governor Veniamin Kondratyev described the attack as "massive", and said at least 12 houses had been damaged. One woman was reportedly injured.
Russia's SHOT Telegram news channel also reported that the bombings had sparked a fire at the Ilsky oil refinery in the area.
A source at Ukraine's SBU security service has now claimed the drones hit both a pumping station and the oil refinery.
They said that at least 20 explosions were heard and that pumping operations had been suspended due to the damage.
The SBU source claimed the targeted facilities had been helping to support Russia's military action in Ukraine.
The Caspian Pipeline Consortium confirmed in a statement that its Kropotkinskaya pumping station, which supports Kazakhstan's main oil export pipeline in Russia, had been damaged.
The pipeline, whose shareholders include US energy giants Chevron and ExxonMobil, handles almost all of Kazakhstan's oil exports, which account for around 1% of global daily supply.
