Ukraine’s military intelligence said on Saturday that its forces struck a major fuel pipeline in the Moscow region supplying Russia’s armed forces, describing the attack as a “serious blow” to Moscow’s military logistics.

According to the Main Intelligence Directorate (HUR), the operation was carried out late Friday and targeted the Koltsevoy pipeline near the Ramensky district. The 400-kilometer pipeline supplies the Russian army with gasoline, diesel, and jet fuel from refineries in Ryazan, Nizhny Novgorod, and Moscow.

HUR said all three fuel lines were destroyed in the attack. The pipeline was capable of transporting up to 3 million tons of jet fuel, 2.8 million tons of diesel, and 1.6 million tons of gasoline annually.

“Our strikes have had more impact than sanctions,” HUR chief Kyrylo Budanov said, referring to international sanctions imposed on Russia following its 2022 invasion of Ukraine.

Meanwhile, a Russian missile strike on southern Ukraine’s Mykolaiv region killed one civilian and injured 15 others, including a child, local governor Vitaliy Kim said. He added that Russia used an Iskander ballistic missile in the attack.

In a separate incident, a Russian strike triggered a fire at a gas plant in the central Poltava region, Ukraine’s emergency service reported.

The attacks came amid continued Russian drone and missile assaults on Ukraine’s energy infrastructure, which Kyiv has condemned as “systematic energy terror.”

Ukraine’s air force said Russia launched 223 drones overnight into Saturday, 206 of which were shot down. Seventeen drones struck targets across seven regions, while another strike hit an agricultural facility in northern Chernihiv, injuring a 66-year-old woman, officials said.
