President Donald Trump held a high-stakes call with Vladimir Putin on Tuesday as the United States seeks a ceasefire between Russia and Ukraine. A White House readout of the call said Putin supports Trump's idea for a mutual pause on energy infrastructure attacks -- but did not include a commitment to the 30-day truce accepted by Ukraine last week despite Trump's optimism in recent days that Moscow would go along.

Russia and Ukraine accused each other on Wednesday of violating a new agreement to refrain from attacks on energy targets hours after it was agreed by U.S. President Donald Trump and Russia's Vladimir Putin.

The White House described it as the first step in a “movement to peace” that it hopes will include a maritime ceasefire in the Black Sea and eventually a full and lasting end to the fighting.
