A phone call between President Donald Trump and Russian President Vladimir Putin included talk of a prisoner swap involving nine Americans and nine Russians, a report said.

Few details were known about Monday's call, aside from Trump's reported attempt to initiate peace talks aimed at ending the ongoing conflict in Ukraine.

After Trump’s third phone call with Putin since his inauguration, it appears there will be no letup in fighting and less U.S. pressure on Moscow.

President Trump said ceasefire negotiations would begin "immediately," but the Kremlin has expressed little eagerness for a ceasefire in the war it began.

The Kremlin has withstood pressure for an immediate cease-fire as a precondition for peace talks, but the Russian president’s push for normalizing relations with the United States appears in limbo.

President Donald Trump's phone call with Russia’s Vladimir Putin did not achieve great strides on ending the war in Ukraine

Vladimir Putin and Donald Trump discussed what the U.S. leader called "impressive" prospects for ties between their two countries in a phone call on Monday, the Kremlin said, adding that Russia and the United States are working on a new prisoner swap.

President Donald Trump and Russian President Vladimir Putin discussed the war in Ukraine and other matters by phone for two hours on Monday. The conversation yielded no breakthrough on efforts to end the largest ground war in Europe since World War II. A ceasefire seems as far as ever.
