President Donald Trump recently took to social media to claim that Russia and Ukraine have agreed to an energy ceasefire - without giving further details.

US correspondent Kate Fisher says there's been no word from Moscow about this arrangement - and it follows Trump's calls for Ukraine to oust Zelenskyy.
