Trump has appeared increasingly exasperated over Russia’s refusal to halt the bombardment of Ukrainian cities.

President Donald Trump framed his Friday summit with Vladimir Putin as a moment to feel out the Russian leader’s parameters for ending the war in Ukraine and acknowledged it would take further meetings to strike a final peace deal.

Prime Minister Mark Carney and Ukrainian President Volodymyr Zelenskyy spoke by phone Monday, reaffirming their agreement that Ukraine must be a party to any discussions about a possible end to the war in that country.
