A group of percussion drones was observed moving west in the southern Kharkiv region, according to an announcement by the Air Force of Ukraine early on September 14th, 2025, at 3:00 AM UTC. The specific timing of this observation within the past hour has not been detailed. This aerial activity follows earlier reports of a drone strike that caused a fire at the Cyrish Refinery in Kirishi, Leningrad Oblast, Russia, which was reported between 12:46 AM and 1:15 AM UTC on September 14th. The refinery, with an annual oil processing capacity exceeding 20 million tons, experienced an impact at coordinates 59.4473472, 32.0402366, as indicated by Exilenova+ reports. These reports also described the fire's progression with the phrase "Objective control of the lesion, well burns 😎." Earlier, on September 14th, around 12:00 AM UTC, a Russian Iskander SRBM system was sighted on the E28 highway near Kudryavtsevo in the Kaliningrad region, a position that places six NATO countries within its potential range, according to a social media post by @cyber_boroshno. These events occurred within a context of heightened aerial activity, including earlier Ukrainian Air Force reports on September 13th of drone movement in the Poltava region towards Kremenchuk and the launch of managed aviation bombs targeting Sumy and Donetsk regions. Poland had also issued air raid warnings in its Lubelskie Voivodeship, leading to the closure of Lublin Airport, due to aerial attack threats.
