Ukrainian President Volodymyr Zelenskyy claimed on Tuesday that Russian President Vladimir Putin is preparing for "new offensive operations."

Whether the U.S.-Russia summit can lead to a deal to produce peace in Ukraine more than 3 1/2 years after Moscow’s invasion remains to be seen.

The U.S. president is pushing to end the war in Ukraine, but analysts say the Russian leader could turn a hastily planned meeting to his advantage.
