<h1>Russia attacks Ukraine's power grid; talks of US Tomahawk transfers heighten tensions and spur calls for tighter sanctions.</h1> Russia struck Ukraine's electrical grid and energy infrastructure, causing injuries, damage, and blackouts across several regions as part of a campaign to degrade critical infrastructure before winter. Ukrainian authorities reported extensive aerial attacks using drones, missiles, and glide bombs and emphasized air-defence interceptions. Parallel diplomatic discussions about supplying long-range precision weapons, including Tomahawks and ATACMS, have heightened tensions, prompted Ukrainian calls for tighter secondary sanctions on Russian oil buyers, and elicited public concern from Russian and allied officials about escalation and arms-transfer policy.
