A ceasefire neither side agreed to

Ukraine resumed its strikes on Russian oil refineries after Volodymyr Zelenskyy said Kyiv was abandoning a ceasefire declared by Donald Trump the previous week - one that neither Russia nor Ukraine said they had agreed to. The Kremlin accused Ukraine of derailing US peace efforts by returning to the attacks on refineries.

Trump's warning on diesel refineries

In an interview aired on Thursday, the US president told Newsmax: "All he's doing is making the world oil price higher. Well, I think that's a disgrace". He said hitting diesel refineries was no good service to the world, because diesel is needed globally, and added: "I'm not a big fan of Zelenskyy".

Ties between Kyiv and Washington had already been strained the week before, when Trump eased sanctions on Russia in exchange for Moscow releasing large amounts of diesel on to global markets. Zelenskyy criticised that agreement, saying it would allow Russia to press on with its full-scale invasion, which began more than four and a half years ago. US efforts under Trump to end the war have so far made no progress.

Zelenskyy: Russia may press on

Zelenskyy said the Kremlin had "launched yet another vile drone strike on Ukrainian energy infrastructure" in Lutsk, causing blackouts.

• Zelenskyy abandoned the Trump-declared energy ceasefire, which neither country said it had joined
• Russia responded by accusing Ukraine of derailing US peace efforts
• The Lutsk drone strike cut power to parts of the city

Starlink disruption and European reassurance

Ukraine said Starlink services had been restricted this week, in effect hobbling Ukrainian drone strike missions and crucial air defences. During a visit to London, Zelenskyy said the sudden restriction left him feeling personally betrayed by Trump and lamented losing a partner.

British defence secretary Wes Streeting said on Thursday that his US counterpart, Pete Hegseth, had assured him in a face-to-face meeting that the satellite communications system had been restored. Streeting told the BBC the cause of the disruption was unclear, saying: "This is not the first time we've seen a falling out between Washington and Kyiv."

Zelenskyy met Nato chief Mark Rutte in Brussels and held a string of bilateral meetings. Emmanuel Macron said after meeting him it was "crucial" that Ukraine receive "all the means necessary to protect itself". Polish prime minister Donald Tusk posted online: "I can reassure you, dear Ukrainian friends and President Zelenskyy: YOU ARE NOT ALONE."

Zelenskyy was set to join an EU summit on Friday.
