KYIV, Ukraine (AP) — Powerful explosions from shelling have hit Ukraine’s Zaporizhzhia region, the site of Europe’s largest nuclear power plant. The International Atomic Energy Agency said more than a dozen blasts shook the Russian-occupied facility on Sunday, damaging buildings and equipment. Ukraine blamed Russia, saying it was trying to prevent the plant from partially restarting to deliver electricity to millions of Ukrainians who are without heat, power or water in the freezing cold. The Russians blamed Ukrainian forces. Elsewhere, Ukrainian President Volodymyr Zelenskyy said over 400 Russian strikes hit Ukraine’s eastern regions on Sunday alone. He also said blackouts were scheduled Sunday night in 15 regions of Ukraine and the city of Kyiv. More blackouts were scheduled for Monday.
