President Trump said on Thursday that a phone call with President Vladimir V. Putin of Russia had not resulted in any movement toward ending the war in Ukraine, adding that he was “not happy” with the conflict grinding on. “I didn’t make any progress with him at all,” Mr. Trump told reporters.

While discussing the situation around Iran, Putin emphasized the need to resolve all issues by political and diplomatic means, said Yuri Ushakov, his foreign affairs advisor.

Trump said after Thursday's conversation that he did not think Putin was looking to stop the war. Kremlin spokesman Dmitry Peskov told reporters that Putin told Trump that Russia expects to agree a date for a third round of peace talks with Ukraine,
