Kate Adie introduces dispatches from the Turkey-Iran border, Russia, the USA, Paraguay and Transylvania.

Israel’s attacks on Iran led thousands of people to flee cities under fire - now they must decide whether to return home, fearing further strikes and a regime still in power. Orla Guerin has been on the Turkey-Iran border, where she spoke to Iranians escaping the war, and others going back home to their families still in the country.

The herbal drink Mate is hugely popular in Argentina - football legend Lionel Messi is a big fan. But across the border in Paraguay, Jane Chambers finds Mate enthusiasts are miffed that their bigger neighbour is seen as the originator of Mate, claiming Paraguay is the true home of Mate culture.

And finally, in Transylvania, Sara Wheeler explores the ebb and flow of a centuries-old Saxon settlement nestled amid ancient forests.
