Russia bombarded Ukraine’s energy infrastructure in waves on Tuesday, with dozens of missiles and hundreds of drones, knocking out power across swaths of the country.

Volodymyr Zelenskyy said at least 33 people were killed on Monday when Russia twice bombed a school used for aid distribution in Komyshuvakha, in the Zaporizhzhia region, and that about 50 people were still believed buried under the rubble. The Kyivvodokanal utility said that the capital’s water supply was suspended because the main water facilities were left without power after the attacks. Operator DTEK said the attacks knocked three of its thermal power plants completely offline. The U.S.-mediated tripartite talks in Abu Dhabi are set for November 10 and 11. German Chancellor Friedrich Merz said it was important that Russia seriously and effectively engage in ceasefire negotiations.
