Ukraine's President Volodymyr Zelensky warned that Moscow "must not receive any rewards" for its ongoing military assault on his country, ahead of the summit in Alaska on Friday between Russian leader Vladimir Putin and President Donald Trump.

During the press conference, U.S. President Donald Trump added that he was "a little bothered" by Zelensky's words regarding "constitutional approval" for land swaps as part of a potential peace agreement.

As Donald Trump prepares for a pivotal meeting with Vladimir Putin, his unexpected praise for the Russian leader caused outrage.
