World at One: News, analysis and comment from BBC Radio 4

There are estimates that are released by the Ukrainians and by the UK MoD, which say that we've now gone past a million Russian casualties and 250,000 this year alone. That's dead and wounded. It's lower on the Ukrainian side, but certainly they seem to be taking more casualties because the Russians are quite happy to be pretty callous with their people and throw them in because they're calculating they can wear the Ukrainians down."
