The upcoming summit between President Donald Trump and his counterpart Vladimir Putin is being used by the Kremlin to divide the U.S. from Europe over the war in Ukraine, according to analysis.

U.S. President Donald Trump said on Monday that both Ukraine and Russia would have to cede land to each other to end the war and that his talks with Russian President Vladimir Putin would be aimed at taking the temperature on a possible deal.

Ukrainian forces are increasing the intensity of long-range drone strikes deep into Russia ahead of Friday's planned meeting between Presidents Trump and Putin.
