Moscow pounded Ukrainian power infrastructure with drone and missile strikes on Saturday and Kyiv launched a deadly strike of its own on southwestern Russia, a day before talks involving senior European and US officials aimed at ending the war were set to resume.

Ukrainian President Volodymyr Zelensky said Ukrainian, US and European officials will hold a series of meetings in Berlin in the coming days, adding that he will personally meet with US President Donald Trump’s envoys.

“Most importantly, I will be meeting with envoys of President Trump, and there will also be meetings with our European partners, with many leaders, concerning the foundation of peace — a political agreement to end the war,” Zelensky said in an address to the nation late Saturday.

Trump’s special envoy Steve Witkoff and his son-in-law Jared Kushner are traveling to Berlin for the talks, according to a White House official, who spoke on condition of anonymity.

American officials have tried for months to navigate the demands of each side as Trump presses for a swift end to Russia’s war and grows increasingly exasperated by delays. The search for possible compromises has run into major obstacles, including which combatant will get control of Ukraine’s eastern Donbas region, which is mostly occupied by Russian forces.
