Ukrainians reflect on four years of war

It's officially four years since the war in Ukraine began. One of the striking things that has happened to mark it has been a united statement of encouragement for Ukraine from leaders of the G7 group of countries, including the US. We hear from a Ukrainian mother and son about the impact of four years of war on their lives and the decisions they've made. Also in the programme: Russian dissidents tell the BBC they’ve seen fellow troops executed on commanders’ orders during the conflict; a look at what might be coming up in President Trump’s State of the Union address; and why a nineteenth-century Ghanaian artefact is being kept from public view.(Photo: People take part in a protest against Russia's invasion of Ukraine to mark the fourth anniversary of the start of the war, in Zurich, Switzerland, 24th February 2026.
