Ukraine launched a significant drone attack on Moscow Thursday, targeting oil refineries and causing fires within the capital city and surrounding areas. This marks Ukraine’s largest drone assault on Moscow in years, escalating tensions in the ongoing conflict. President Zelensky defended the attack, characterizing it as a “justified response” to recent Russian strikes on Ukrainian territory. The attack specifically targeted oil infrastructure, aiming to disrupt Russia’s war efforts, according to Ukrainian officials. Russian authorities reported extinguishing the fires, but the incident highlights Ukraine’s growing ability to reach deep inside Russian territory. The Kremlin has not yet issued a comprehensive response to the attacks, but is expected to condemn the action as a terrorist act. This latest development signals a potential shift in Ukraine’s strategy, moving the conflict more directly onto Russian soil.
