**Deck**: Ukrainian drones struck an oil refinery, electronics and chemical plants, and a shopping centre deep inside Russian‑held territory, while Russia’s defence ministry said air defences shot down hundreds of UAVs. The attacks pushed the war further into Russia’s industrial interior and left civilians injured in Ulyanovsk.

Drone strikes on 25 September pushed the war deeper into Russia’s industrial heartland, with Ukrainian UAVs hitting energy, electronics and chemical sites as well as a shopping centre in occupied territory. Russian authorities reported civilian injuries and damage to housing and factories in several regions.

Russia’s defence ministry said its air defence systems shot down 592 Ukrainian unmanned aerial vehicles overnight over Russian regions and the Black Sea. That figure cannot be independently verified from available reporting, but would represent an exceptionally large salvo if accurate. Large‑scale drone attacks were reported in the Ulyanovsk, Voronezh, Perm and Rostov regions.

In Ulyanovsk, officials reported damage to both industrial and civilian infrastructure, including residential buildings. Eight people, including a child, were injured. Authorities there did not immediately detail which specific sites were hit, but the region featured prominently in the overnight raids.

One of the most significant reported targets was the Permnefteorgsintez oil refinery in the city of Perm. Ukrainian long‑range drones attacked the facility in the morning, resulting in several large fires. The Perm refinery is Russia’s seventh‑largest and can process up to 13 million tons of crude oil per year, making it a key node in the country’s fuel system.

A separate Ukrainian strike hit the Iskra Electronics Plant in Ulyanovsk. Video from the scene shows six consecutive drone impacts on different parts of the facility. The plant specialises in electronic components, radio‑electronic equipment and communications systems for military and industrial sectors, placing it squarely within Russia’s defence‑industrial base.

In Voronezh, Ukrainian drones struck the Voronezhsintezkauchuk synthetic rubber plant, causing a fire. The facility produces thermoelastoplasts and synthetic rubbers. Overnight, Ukrainian mid‑range drones also hit the Stroycenter shopping centre in Luhansk City, under Russian occupation, triggering a large fire.

The combination of civilian casualties in Ulyanovsk, fires at energy and industrial plants in Perm and Voronezh, and damage to commercial property in Luhansk underlines how far the conflict has moved beyond front‑line regions. Industrial facilities that once functioned as routine workplaces are now part of a contested battlespace.

The extent of lasting damage at the Perm refinery, the Iskra Electronics Plant, the Voronezhsintezkauchuk plant and the Stroycenter shopping centre will determine how disruptive this wave of strikes proves to be. Key signals to watch include repair timelines at these facilities, visible changes to security and protection measures around similar sites, and whether either side adjusts the tempo or targets of its long‑range drone campaigns.
