President Donald Trump said on Tuesday he thinks President Vladimir Putin wants to stop Russia's war in Ukraine, despite recent attacks against the beleaguered nation.

Russian President Vladimir Putin on Monday declared a unilateral three-day ceasefire in Ukraine next month, a move met with skepticism by Ukrainian officials who demanded the Kremlin leader immediately accept a longer truce proposal from the United States that he has so far rejected.

US President Donald Trump has not said whether he trusts Kremlin leader Vladimir Putin, but suggested that Putin "would like to stop the war". Trump has added that if he had not won the election, Putin would have taken "over all of Ukraine".
