Ukrainian forces have intensified their long-range strikes against military and energy infrastructure across Russia, hitting various strategic targets including a military plant in St. Petersburg and an oil refinery deep inside Russian territory. The attacks, which utilized Ukrainian-made Flamingo missiles, came as a surprise during significant Russian events, such as the opening of the St. Petersburg economic forum. Reports indicate that the strikes ignited fires at oil facilities and prompted Russian officials to acknowledge issues with fuel supplies in the aftermath of these assaults. Ukrainian drones have also targeted naval assets in the Baltic, marking a significant escalation in the conflict as both sides prepare for a prolonged confrontation.
