Ukrainian Drones Hit Kazan High-Rise in Escalating Conflict

In a dramatic escalation of the ongoing conflict, Ukrainian drones hit the Russian city of Kazan on Saturday, marking a rare attack deep into Russian territory.

A high-rise apartment building in the city of 1.3 million was damaged, but thankfully no injuries were reported.

Videos shared on Russian social media showed drones crashing into buildings, creating fiery explosions.

Kazan, located in Tatarstan, has been targeted before, but this latest strike shifts the focus from industrial sites to residential areas, according to local officials.

Authorities evacuated some residents and temporarily closed Kazan’s international airport, one of Russia’s busiest.
