Russia tries to freeze Ukraine as it suffers record casualties and retreats

What Happened

According to the Ukrainian military, Russian forces suffered 46,230 killed or wounded in September 2026, the highest monthly casualty count of the year, including a reported 2,090 casualties on September 28. Al Jazeera cannot verify these figures. Ukraine's Third Army Corps said Operation Vivaldi reclaimed 176 sq km around Lyman through a feigned attack from the west and an assault from the north, using remotely operated Russian armoured personnel carriers packed with explosives. Russia denied the gains, but the Institute for the Study of War and DeepState assess Russia's net territorial gains this year at 148 sq km, far below Russia's claimed 5,300 sq km. Russia also intensified strikes on energy and civilian infrastructure. Several people were killed on September 28 when a drone destroyed part of the National Academy of Sciences in Kyiv; on September 30 drones struck a thermal power plant in the Kyiv region, causing power outages, with at least five killed nationwide. Ukraine's defence ministry electronics adviser Serhii Beskrestnov said Russia tested a drone with a cumulative cutting warhead designed to destroy high-voltage pylons. In the week ending October 1, Ukraine downed 81 percent of 1,933 long-range aerial drones; President Volodymyr Zelenskyy reported a 55 percent interception rate for jet-powered Shaheds. Ukraine conducted deep strikes on Russian refineries and defence plants, including the Perm and Novoshakhtinsk refineries on September 25, the Ilsky refinery on September 26, the NPP Zavod Iskra electronics plant, and the Efremovsky Synthetic Rubber Plant. Both countries have outspent their 2026 defence budgets; Ukraine is seeking an additional $27bn in meetings with the European Commission.

Key Actors

Why It Matters

The combination of record Russian casualties, limited territorial gains, and escalating drone strikes on energy infrastructure signals a grinding attritional phase ahead of winter. Russia's shift to jet-powered drones and new warheads against pylons threatens Ukraine's power grid and digital connectivity, while Ukraine's deep strikes aim to degrade Russian fuel and missile production. Budget overruns on both sides underscore the economic strain of sustaining high-intensity operations into 2027.

Watch For

Monitor whether Ukraine secures funding or interceptor manufacturing licences after US President Donald Trump retracted the Patriot licence offer; watch for further Russian strikes on high-voltage lines and data centres, and for Russia's planned $12bn investment in jet-powered drones and loitering munitions next year. Territorial claims around Lyman and Donetsk will be tested by ISW and DeepState open-source mapping, and indications of Ukraine's additional $27bn financing from the European Commission may emerge.
