Ukrainian intelligence agencies have ramped up their operations within Russia, successfully assassinating high-ranking military officials, including Lt Gen Igor Kirillov. This marks a significant escalation in their activities, as attacks are now occurring within the Russian capital, raising concerns about Russian security measures. Following recent assassinations of military figures and notable individuals linked to the regime, the Ukrainian SBU’s ability to carry out such operations signals a potential shift in the balance of covert warfare between the two nations.
