The Ukrainian President offered some of his sharpest criticism of Donald Trump after this week's third mass-casualty Russian attack.

Trump said on Friday that Russia had agreed to supply diesel to the global market to ease fuel prices. Kyiv's allies are not supportive.

Rosatom said the International Chamber of Commerce agreed that a Finnish firm wrongly terminated the contract for a new nuclear power plant.

The Kremlin also said Putin and Trump discussed major economic initiatives during the phone call, including potential supplies of Russian fuel.
