Ret. Lt. Gen. Keith Kellogg joined'Your World' to discuss NATO holding nuclear exercises and recent Iranian-made'kamikaze' drones striking Kyiv. Russian drone and missile attacks have destroyed nearly a third of Ukraine's power stations, but Ukrainian forces continue to gain ground President Volodymyr Zelenskyy announced Tuesday. Russia has launched barrages of missiles, shells and other ordnance into Ukrainian cities in a campaign that started after the bombing of the Kerch Bridge on October 8. The attacks have targeted population centers, parks and infrastructure as Ukraine's cold winter approaches. "Since Oct 10, 30% of Ukraine's power stations have been destroyed, causing massive blackouts across the country," Zelenskyy announced Tuesday.
