Zelensky offers concession on NATO, Russia still impediment to peace deal, Trump vows consequences for ISIS attack on U.S. troops.

Deputy foreign minister Sergei Ryabkov reiterated that Moscow would not give back land to end the war, and would not accept any Nato peacekeepers stationed in a post-war Ukraine. As Russia was accused of stalling efforts to end the conflict, hundreds of thousands of people were left without power in Ukraine following heavy bombardment nationwide.

Zelensky said on Sunday he was already in Berlin ahead of talks with a U.S. delegation on Monday. Axios reported on Friday he would meet with President Donald Trump's Russia envoy, Steve Witkoff, and the president's son-in-law, Jared Kushner, in Germany.
