On February 25, during the ongoing conflict between Ukraine and Russia, a fibre-optic FPV drone operated by Russian armed forces was recorded attacking the Kyivskyi district in Kharkiv, marking the first such incident in this city since the onset of Russia’s full-scale invasion of Ukraine. The drone reportedly struck a tree in the area. This event demonstrates the increasing reliance on advanced drone technology in combat situations, reflecting a shift in tactics employed by the Russian military.

The Kharkiv Oblast Prosecutor's Office has noted that this incident is not only significant due to the use of new warfare technology but also raises serious legal implications under international law. The prosecutor's office has initiated a pre-trial investigation into this incident under Article 438.1 of the Criminal Code of Ukraine, which pertains to war crimes. This move underscores the country's commitment to holding offenders accountable for violations during the conflict, particularly as drone warfare becomes more prevalent.

The use of fibre-optic drones signifies a potential escalation in the Russian military strategy, adding a new dimension to the ongoing conflict in Ukraine. As both sides continue to adapt to advances in technology, the implications for urban warfare in cities like Kharkiv could be profound, complicating efforts for civilians and military personnel alike. The international community will likely keep a close eye on how these developments play out, especially in relation to the adherence to the laws of war.
