Ukrainian President Volodymyr Zelenskiy said on Saturday that the end of the more than 2-1/2-year-old war with Russia depended on the "resolve" of Kyiv's Western allies in providing needed weaponry and permission to use it.

Russia has been waging an aerial bombardment campaign on Ukraine's power grid since autumn 2022 after invading the country earlier that year. It has damaged or destroyed most of Ukraine's thermal power generating capacity and has sometimes hit dams, but has not yet struck any Ukrainian-controlled nuclear facilities.
