Donald Trump has called Ukraine’s renewed strikes on Russian oil refineries a “disgrace”, while renewing his criticism of Volodymyr ⁠Zelenskyy after an energy ceasefire between Russia and Ukraine collapsed.

Ukraine resumed strikes on Russian oil refineries ⁠after Zelenskyy said that Kyiv was abandoning a ceasefire abruptly and declared by Trump last week, one that neither Russia nor Ukraine said they had agreed to.

“All he’s doing is making the world oil price higher. Well, I think that’s a disgrace,” the US president told the Newsmax news outlet in an interview aired on Thursday.

“There are a lot ‌of targets you can ‌hit, but when you shoot at diesel refineries where you make, you know, ‌diesel oil, and we need that, and the world needs that, then he’s not doing a good service for the world.”

Relations between Kyiv and Washington have soured since last week, when Trump eased sanctions on Russia in exchange for Moscow releasing large amounts of diesel on to global markets.

Zelenskyy slammed the agreement, which was widely interpreted as an attempt to curb high fuel prices ahead of the US midterm election, saying it would allow Russia to press on with its full-scale invasion of Ukraine that began more than four and a half years ago. US efforts under Trump to end the war have made no progress.

Trump repeated to Newsmax his views of the two leaders involved in the conflict. “I’m not a big fan of Zelenskyy,” Trump said. “I think they actually both would like to see it ⁠end, but I think I find Zelenskyy to be more difficult ​to deal with ​than Putin.”

Kyiv’s relationship with Washington was strained further this week when Ukraine said Starlink services had been restricted, in effect hobbling Ukrainian drone strike missions and crucial air defences with a flick of the switch.

During a visit to London this week, the Ukrainian president said the sudden restriction of Starlink had left him feeling personally betrayed by Trump and lamented losing a partner.

British defence secretary Wes Streeting said on Thursday his US counterpart, Pete Hegseth, had assured him in a face-to-face meeting that the vital satellite communications system had been restored. In an interview with the BBC, he said it was unclear what had caused the disruption, but added: “This is not the first time we’ve seen a falling out between Washington and Kyiv.”

Amid growing doubts about long-term US commitment to Ukraine, European leaders have shown their support for Zelenskyy, who met Nato chief Mark Rutte in Brussels and held a string of bilateral meetings before he was set to join an EU summit on Friday.

After meeting Zelenskyy, French president Emmanuel Macron said it was “crucial” that Ukraine receive “all the means necessary to protect itself”.

“I can reassure you, dear Ukrainian friends and President Zelenskyy: YOU ARE NOT ALONE,” Polish prime minister Donald Tusk posted online.

As he met with Macron in Brussels, Zelensky said that the Kremlin had “launched yet another vile drone strike on Ukrainian energy infrastructure” in the city of Lutsk, which caused blackouts.

The Kremlin meanwhile accused Ukraine of derailing US peace efforts by resuming its strikes on refineries.
