The European Union's top diplomat, Josep Borrell, has urged Ukraine's allies to lift restrictions on the use of weapons provided to Ukraine, enabling strikes on military targets inside Russia. This request comes amid a significant escalation in the conflict, with Ukraine beginning to use F-16 fighter jets in combat, provided by U.S. allies. Russian forces responded with massive drone and missile barrages, targeting Ukraine's power infrastructure and causing widespread blackouts and civilian casualties. Ukrainian President Volodymyr Zelensky has reiterated the need for long-range capabilities to counter these attacks. The U.S. remains cautious about providing such capabilities to avoid escalating the conflict further with nuclear-armed Russia.
