In a significant escalation of hostilities, Ukraine launched a massive drone offensive against various targets in Russia, reportedly deploying over 500 drones in a coordinated attack. The most severe impacts were felt in the Moscow region, where at least four people are confirmed dead and many injuries have been reported following strikes on residential areas and key infrastructures, including oil refineries. Russian state media described these attacks as the largest on Moscow in over a year, with drone strikes igniting flames at the Ryazan refinery and elsewhere. Ukrainian officials, including President Zelenskyy, have expressed gratitude towards their military forces for these strikes, asserting a commitment to continue such operations in response to previous assaults on Ukrainian territory. Amid this surge in drone warfare, airports in Moscow were temporarily closed, reflecting the heightened state of alert in the capital.
