Russian President Vladimir Putin does not want to end the war in Ukraine, Donald Trump has said as he raised the prospect of more sanctions on Russia. The U.S. president told reporters aboard Air Force One that he was "very unhappy" with his earlier phone call with the Russian leader as Moscow said it would continue to pursue its war aims.

The Russian bombardments sent Ukrainians scurrying for shelters across the country and came after the call between Trump and Putin, which ended without a breakthrough.

Russia unleashed a record air strike on Ukraine as US President Donald Trump expressed disappointment over his latest phone call with Vladimir Putin aimed at bringing an end to the war.
