Ukraine launched a significant wave of drone attacks targeting Moscow and its surrounding areas early Thursday, hitting an oil refinery and other infrastructure. This coordinated assault is considered one of the largest strikes on the Russian capital since the commencement of the invasion. Eyewitnesses reported explosions across Moscow, and the drone activity forced the temporary closure of the city's main airports, with flights halted and passengers evacuated. The attack on the oil refinery resulted in ignitions and damage, underscoring the strategic targeting of Russian energy assets. This escalation follows a period of heightened Russian aerial bombardments on Ukrainian cities, including Kyiv. The Ukrainian response, utilizing a substantial number of drones, signifies a shift in the conflict's dynamics, bringing the war's impact directly to the heart of Russia. The timing of the attack, just prior to a NATO meeting, adds a further layer of international significance.
