On the night of February 16-17, a series of drone attacks targeted various locations across Russia, primarily affecting the Ilsky oil refinery in Krasnodar Krai, which erupted into flames following the assault. Reports suggest that drones referred to as Liutyi were involved in these strikes, and local residents reported hearing at least ten explosions near the refinery vicinity. The incident has drawn notable attention due to its implications regarding Russia's vulnerabilities to drone warfare.

Local authorities, specifically the Operational Headquarters of Krasnodar Krai, acknowledged the attack the following morning, confirming that while the refinery suffered significant damage, there were no reported casualties. This situation has raised security concerns not only regarding the refinery but also about the operational capacity of air defense systems, as reports indicated that more than 20 drones were allegedly intercepted by Russian defenses.

The drone strikes have also resulted in airport closures and power outages in Kazan, suggesting a wider operational impact beyond just the refinery. The ongoing situation underscores the continuing strain and escalation in hostilities linked to the broader conflict involving Ukraine and Russia, highlighting developments in military tactics and technologies involved in the confrontation.
