Kate Adie presents stories from Ukraine, Malawi, Switzerland and Germany.

Bakhmut has long been a prize for Russian forces since it invaded Ukraine a year ago. Tens of thousands of troops have died in a protracted fight for the city, in what is the longest battle of the war so far. Quentin Sommerville has been travelling through the front line, and reveals the changing nature of the war.

A 14-day period of national mourning is underway in Malawi, after more than 200 people died when the country was hit by Cyclone Freddy. More than 200,000 people have been displaced. Rhoda Odhiambo visited Malawi’s commercial capital, Blantyre, which is among the worst-affected areas.

Korean TV dramas have also been a huge hit - and Sophie Williams says one show in particular has put a small village in Switzerland on the map.
