Crossing into unknown territory

Refugees cramming onto trains brings back memories of the Second World War, amid an invasion that heralds a grim new political reality The war in Ukraine has brought back some uncomfortable memories. Refugees crowding on to trains in eastern European snow to escape a war. Young men volunteering to fight for their country and being sent into harm's way with almost no training. And the possibility that a new Cold War between Russia and the US and Europeans could be upon us, says Jeremy Bowen. When Belarus opened its country to tens of thousands of mostly Middle Eastern migrants and refugees last year and started pushing them across the border into Poland, most Poles supported the government’s refusal to let them in. Yet Poland is now facing a refugee crisis on a much bigger scale. Close to two million people, have crossed into Poland in just three weeks. Adam Easton met one of those Poles and the refugee he is supporting. Attempts to create humanitarian corridors over recent weeks from besieged cities like Mariupol and Kharkiv have frequently been stymied by continued Russian attacks, imperilling efforts by residents to flee. At the border between Poland and Ukraine, Kasia Madera met one woman travelling from Kharkiv to Germany with her children. Australia’s east coast has seen some of the worst flooding in the country’s history over recent weeks with more than 20 people killed in intense downpours. Viv Nunis met some of the residents whose homes had been destroyed. China was the place where Covid-19 first emerged, but it was also the first place to get back to something resembling normality. But that all changed this week, as new cases jumped - and authorities imposed draconian new restrictions to maintain its 'zero Covid strategy'. Normal life for tens of millions of people, says Robin Brant in Shanghai - has stopped, again. Presenter: Kate Adie Producer: Serena Tarling Editor: Emma Close
