Can the Ukrainians take back Kherson - and what would it mean for the wider conflict?

Ed Arnold, research fellow at the defence thinktank RUSI, tells Sky News: "Reporting suggests the Ukrainians have broken the first barriers of defence around Kherson. "The first tends to be the weakest - but essentially they are closing in on the city, which they have been doing for some time." ...Mr Arnold says the Ukrainian's counteroffensive looks set to be "methodical and measured". "They have between three and five axes of advance. They've been thinking about this for a long time. "They're resisting the temptation to do what the Russians tried and failed to do in Kyiv, which is raze the city and then just walk in."
