币界网报道：Ukraine has urgently appealed for additional air defense systems following a massive overnight assault by Russian forces involving 477 drones and 60 missiles, marking one of the largest coordinated attacks since the invasion began. Ukrainian officials reported that the strikes targeted critical infrastructure, military installations, and civilian areas across multiple regions, causing significant damage and casualties. President Volodymyr Zelensky emphasized the need for advanced missile defense technology, including Patriot systems, to counter the escalating threat. The attack underscores Russia's intensified strategy to overwhelm Ukraine's defenses through sheer volume, exploiting gaps in air cover. Ukrainian forces managed to intercept a portion of the incoming threats, but the scale of the assault exposed vulnerabilities in existing defense capabilities. NATO allies are under mounting pressure to expedite deliveries of pledged systems, while Kyiv warns of further destabilization if support lags. The assault comes amid stalled Western aid packages and growing concerns over Ukraine's ammunition shortages. Analysts suggest Russia aims to degrade Ukraine's energy grid and morale ahead of anticipated spring offensives. The incident has reignited debates over long-term security guarantees for Ukraine, with calls for faster integration into European defense frameworks. Civilian resilience is being tested as repeated strikes disrupt power, heating, and water supplies during winter. The UN condemned the attacks as violations of international humanitarian law, citing disproportionate harm to non-combatants.
