Questions remain about minerals deal, but one thing seems sure - Zelensky will visit DCpublished at 20:50 Greenwich Mean Time 26 February

Last night, a senior Ukrainian official told the BBC that the terms of a deal - to allow the US access to rare Ukrainian minerals - had been agreed.
Reports suggested a US request for $500bn (£395bn) in potential revenues from using Ukraine's natural resources had been dropped. But we also learnt that Ukrainian security guarantees had not made their way into the deal - something Kyiv has been pushing for.
Twenty-four hours later, little more is known. Ukraine's President Volodymyr Zelenksy has said it's important that at least a "sentence" about guarantees is included, but US President Donald Trump reiterated his stance that such assurances should be made by Europe, Ukraine's "next door neighbour".
We do, however, know Trump and Zelensky will thrash out the terms of the agreement in a meeting in Washington DC on Friday. Trump said so during his first cabinet meeting - during which he also hinted at a possible Russia-Ukraine ceasefire, suggesting Russian President Vladimir Putin would need to make "concessions" for that to happen.
It's a busy end to the week for the US president, who's also hosting UK Prime Minister Keir Starmer - tomorrow - for talks where Ukraine is at the top of the agenda.
We'll be back tomorrow to cover that meeting live, as well as developments from on the ground in Ukraine, but for now we're ending our live coverage there. In the meantime, there's lots for you to read across the BBC News website:
