Biden, Zelensky sign landmark US-Ukraine security deal: AFP

Presidents Joe Biden and Volodymyr Zelensky signed a landmark US-Ukraine security deal on Thursday, as the US leader warned Russia’s Vladimir Putin they were “not backing down”.

Hailing the bilateral accord and a G7 deal for a $50 billion loan for Ukraine using frozen Russian funds, Biden said that they “collectively show Putin he cannot wait us out, he cannot divide us.”
