'Time for Ukraine to get new president,' says Trump after Zelensky condemns diesel deal

US President Donald Trump has said he thinks "it's time for Ukraine to get a new president" as he responded to Volodymyr Zelensky's criticism of the US diesel deal with Russia.

The Ukrainian president warned a new deal to release millions of tonnes of Russian diesel into the US would provide Moscow with money to continue its war against his nation, calling it a gift to Russian President Vladimir Putin.

Trump told reporters outside the White House on Saturday that Zelensky "wants to make problems for the world" by continuing to authorise attacks on Russian refineries.

"He'd better damn well stop," Trump said, before suggesting Ukraine should "get a new leader who can make a deal".

Since Russia invaded Ukraine in 2022 the country has been under martial law, meaning elections are suspended.

Global fuel supplies, including diesel, have been severely limited by the war against Iran launched by the US and Israel, which led to the effective closure of the Strait of Hormuz, through which roughly a fifth of the world's oil products usually flows.

Russia - a major producer - and Ukraine have recently intensified their strikes on each other's energy infrastructure and transport facilities, further straining energy markets.

"We said, 'you can do whatever you want to Russia, don't hit the refineries', because that's a world problem that's caused," Trump continued.
