A drone attack on Kazan, Russia, on 21 December 2024, resulted in damage to residential buildings and casualties. The attack, attributed to Ukraine, employed "Lyuty" drones, capable of long-range strikes, hitting civilian targets. This is viewed as a deliberate act of terrorism, potentially escalating ahead of anticipated political changes in the US and aimed at demoralising the Russian populace. Military experts highlight the ongoing arms race between offensive drone technology and air defence systems, predicting further such attacks. The incident prompted calls to designate Ukraine a terrorist state and strengthen Russia's security measures.
