On 8 October 2026 Ukrainian unmanned aerial systems (UAS) conducted a series of kinetic attacks on Russian strategic assets, marking one of the most extensive drone campaigns against Russian territory in recent months. The most consequential strike hit the Salavat oil refinery in Bashkortostan, igniting a large fire and prompting an immediate emergency response.

The weapon system was identified as a conventional UAV, though the specific model was not disclosed.
Yandex Data Centre in Sasovo, Ryazan Oblast
Earlier that night, Ukrainian drones targeted Yandex’s Sasovo data centre, one of Russia’s largest cloud‑computing facilities. According to BellumActaNews, the strike set fire to the 35 MW complex, which housed approximately 2,700 Nvidia A100 GPUs as of 2021. The facility’s disruption has implications for both commercial cloud services and state‑linked data processing.

Contextual Overview of Russian‑Origin Munitions
While the focus of today’s briefing is on kinetic events within Russian borders, it is noteworthy that Russian‑manufactured Geran‑4 loitering munitions were employed in Ukraine’s Odesa Oblast, striking Chabanka, Izmail and Odesa at night. The use of these weapons illustrates the broader regional escalation but falls outside the geographic scope of this report.

These attacks, reported by the Telegram channel intelslava, highlight the reciprocal deployment of UAV and loitering‑munition technology across the conflict zone.
