The US has stopped sharing intelligence with Ukraine amid Washington's push for a swift deal to end Russia's war.

       A Ukrainian source told Sky News earlier that the intelligence which helps Ukraine attack Russia on Ukrainian territory would continue to be shared.

       But in a follow-up update, the insider told Sky News that: "A few hours ago, the exchange of all information was stopped".

       Frosty relations between the US and Ukraine continue, despite Ukraine president Zelensky pledging to "make things right" with Trump.

       The US President did tell Congress overnight that he had "appreciated" a letter from the Ukrainian leader praising his "strong leadership".

       “I appreciate that he sent this letter… We’ve had serious discussions with Russia and have received strong signals that they are ready for peace. Wouldn’t that be beautiful?" Trump added. “It’s time to stop this madness. It’s time to halt the killing. It’s time to end this senseless war. If you want to end wars you have to talk to both sides.”
