Ukrainian drone attacks on Russian border regions have resulted in at least five deaths and over 20 injuries, Russian authorities report. The attacks impacted the Belgorod, Bryansk, Kursk regions, and even reached Moscow. This marks a significant escalation in the conflict's reach within Russian territory. Details regarding the specific targets and damage are still emerging, but officials confirm civilian casualties. The attacks are likely a response to ongoing Russian aggression in Ukraine, though Kyiv has not officially claimed responsibility. This incident raises concerns about the potential for further escalation and wider regional instability. Russia has vowed to retaliate for the drone strikes.
