WASHINGTON — U.S. President Donald Trump sowed confusion on Sunday, announcing an "energy ceasefire" between Ukraine and Russia that sparked astonishment in Kyiv, silence from Moscow and support from Ukraine's Western allies. But the ceasefire appeared shaky at best as Ukrainian President Volodymyr Zelenskyy said Russia struck multiple Ukrainian power plants on Sunday, including one in the capital and another in Kharkiv, leading to power outages and outrage. Trump's announcement came two days after he declared a temporary easing of U.S. sanctions on Russian diesel, prompting outrage by European allies and Kyiv, who said it would only embolden Russian President Vladimir Putin. "Effective immediately, there is an ENERGY CEASEFIRE in the War between Russia and Ukraine," Trump said early Sunday on Truth Social. "Both parties have agreed. Do not break it!" Zelenskyy appeared to express surprise at the announcement, saying he was seeking further details, but added that "Ukraine supports the ceasefire, and it is important that Russia support it as well." Russia has yet to confirm its agreement
