In an unprecedented overnight operation on July 7, Ukraine executed its most extensive drone strike of the ongoing conflict, deploying over 430 unmanned aerial vehicles towards the Moscow area. While Russian air defense units targeted the drones from afar, 36 were neutralized before reaching Moscow, suggesting that a considerable number successfully breached Russian defenses. Additionally, a significant oil refinery in Siberia's Omsk region was hit in a simultaneous attack. This event follows Ukraine's recent offensive on July 4 against the Kronstadt naval base and oil terminal in St Petersburg, marking a new phase of in-depth strikes within Russia that is challenging Moscow's air defense capabilities.
