WASHINGTON/MOSCOW/KYIV, Aug 16 (Reuters) - U.S. President Donald Trump said on Saturday that Ukraine should make a deal to end the war with Russia because “Russia is a very big power, and they’re not”, after a summit where Vladimir Putin was reported to have demanded more Ukrainian land.

After the two leaders met in Alaska on Friday, Trump told Ukrainian President Volodymyr Zelenskiy that Putin had offered to freeze most front lines if Kyiv ceded all of Donetsk, the industrial region that is one of Moscow’s main targets, a source familiar with the matter said.
