Ukraine's President Zelenskyy warned of global security threats following a Russian shelling attack that cut power to the Chornobyl nuclear plant. The loss of power at the defunct plant, a UNESCO World Heritage site, raised concerns about radioactive material containment. Similar power issues have occurred at the Zaporizhzhia plant. The US is reportedly sharing intelligence with Ukraine for long-range strikes on Russian energy infrastructure, while European nations are discussing urgent measures against "hybrid warfare" and sabotage, including "drone walls" and eastern border defenses. G7 nations also vowed to pressure Russia's oil exports and consider measures against entities financing the war.
