Ukraine strikes Russia, 8 October 2026: Omsk and Salavat refineries, Sasta fire and Yandex outage

A large fire broke out in Sasovo following reports of an attack. According to Astra’s OSINT analysis, published photographs and video locate the fire on the grounds of the Sasta factory.

The company manufactures high-precision computer numerical control (CNC) machine tools, including machining centres and turning and milling equipment. Its products are used in Russia’s defence, aerospace and other industrial sectors.

Sasta’s importance to military production lies in the machine tools used to manufacture complex metal parts and assemblies. The company previously supplied equipment to entities within Tactical Missiles Corporation and Roscosmos. Sasta PJSC is also subject to international sanctions.

The Yandex DC Sasovo data centre is located on the same industrial site. Following the overnight attack, reports emerged of disrupted power supplies and parts of Yandex Cloud infrastructure becoming unavailable.

Published reports said the problems affected computing resources, networks, storage, databases and other cloud services.

For users and businesses, these disruptions can mean losing access to websites, applications and work systems that depend on cloud infrastructure.

Ukraine’s General Staff confirmed a strike on the Gazprom Neftekhim Salavat oil refining complex in Bashkortostan. The Unmanned Systems Forces said operators of their 1st Separate Centre carried out the operation overnight into 8 October. A fire was recorded at the facility.

The complex can process up to 10 million tonnes of hydrocarbon feedstock annually. It produces fuel and petrochemicals and, according to the General Staff, supplies the Russian armed forces. The effects of the strike are being assessed.

During the day on 8 October 2026, Ukraine’s Defence Forces attacked the Omsk oil refinery with upgraded FP-1 drones. Fire Point reported a hit on the target followed by a fire. Video showing smoke near the facility was also published in open sources.
