Ukraine has again accused Russia of committing war crimes, as a viral video appears to show two unarmed Ukrainian soldiers being shot dead as they attempt to surrender.
We look at whether a war crime has been committed, with Kateryna Stepanenko from the Institute for the Study of War, which has been closely monitoring the conflict since day one.
And six months on from the Kakhovka Dam explosion, we explore what is happening in the region and see what archaeologists have found since the waters subsided.
Today’s episode is presented by Victoria Derbyshire and Vitaly Shevchenko.
It was made by Keiligh Baker and the producers were Clare Williamson, Arsenii Sokolov and Ivana Davidovic. The technical producer was Mike Regaard. The series producer is Lucy Boast. The senior news editor is Sam Bonham.
