**Deck**: The United Nations says Ukraine could face its harshest winter since Russia’s full‑scale invasion, as repeated strikes threaten heating, water and sanitation. New attacks on fuel and energy infrastructure in western Ukraine, Taganrog and occupied Mariupol show how both sides are targeting the systems civilians rely on to get through the cold season.

Ukraine is heading into what the United Nations warns could be its most difficult winter of the war. A recent UN assessment says the country may face its harshest cold season since the 2022 invasion, with widespread damage to energy infrastructure threatening to disrupt heating, water and sanitation for millions.

This warning comes as Russia shifts some of its latest large‑scale strikes to regions that had previously seen fewer attacks. On 13 September, Russian forces conducted what one account described as another series of combined strikes on Ukraine, with a mass attack on the western part of the country. Explosions were reported in the Lviv, Khmelnytskyi, Ivano‑Frankivsk, Rivne and Ternopil regions, including an area near the Staroveytovo checkpoint by the Yagodyn border crossing.

Other reporting from the same wave of attacks said that targets in western Ukraine included gas stations and a locomotive that was reportedly carrying military supplies, as well as port facilities near Odesa and Mykolaiv. The strikes reached locations just hundreds of meters from the Polish border.

Ukraine has continued to strike back, but often against infrastructure that also shapes civilian life. In Russian‑occupied Mariupol, Ukrainian strike drones have been targeting energy infrastructure. One building in the city was on fire after Russian air defense activity. Inside Russia, in the city of Taganrog, fuel tanks were still burning on 13 September following an attack the previous night by Ukrainian drones.

For Ukrainians, the practical concern is whether electricity and fuel will hold out as temperatures drop. Heating systems, water supplies and sewage treatment all depend on a functioning grid. The UN warning notes that after multiple waves of attacks, the cumulative damage to power infrastructure raises the risk that outages will last longer and affect more people than in previous winters.

Ukraine’s air‑defense situation adds another layer. The country is working to contract around 1,000 Patriot missiles, but most of these interceptors are not expected to arrive in the near term. Western manufacturers are struggling to increase production fast enough to keep up with Russian cruise missile and drone attacks. Each new large strike on the grid, like the one reported on 13 September, tests a defense system that is already stretched.

Even on days without major hits, the sense of threat rarely lifts. Alerts about drone danger have been issued for Kyiv and several other regions, reminding residents that more strikes could come at any time and that power stations, substations and fuel depots remain attractive targets.

Internationally, the contest over energy infrastructure has become a central part of the war. A country whose grid is repeatedly damaged finds it harder to keep industry running, support displaced people and sustain military operations. For Russia, hitting power and fuel facilities is a way to pressure Ukraine without necessarily advancing front lines.

What will matter most in the coming weeks is whether Russian forces continue large‑scale strikes on energy sites, how quickly Ukrainian teams can repair damage, and how fast promised air‑defense supplies arrive. Concrete improvements to Ukraine’s ability to protect key plants and restore the grid after attacks would be the clearest sign that it can weather the winter the UN now fears.
