Former US President and Republican candidate in the upcoming elections, Donald Trump, has reiterated his pledge to stop the conflict between Moscow and Kiev following his conversation with Ukraine's Vladimir Zelensky on Friday.

Trump wrote in a post on Truth Social that he "had a very good phone call" with Zelensky, during which the Ukrainian politician congratulated him on a "very successful" Republican National Convention and "condemned the heinous assassination attempt."

Trump went on to say that he appreciates Zelensky "for reaching out because I, as your next President of the United States, will bring peace to the world and end the war that has cost so many lives and devastated countless innocent families."
