Ukraine’s President Zelensky says it’s ‘inevitable’ that war is returning to Russia, and two drone strikes on a Moscow skyscraper look like an attempt to prove the point.

Professor of Defence Studies Michael Clarke explains why he’s worried by this, and we assess whether it makes any strategic sense.

Ukraine is manufacturing, and using up, thousands of drones every month. Svitlana Morenets in Kyiv tells us about getting hands on with the ‘army of drones’ programme that is also training thousands of operators.

And British man Aiden Aslin, who went to fight Daesh in Syria and then joined Ukraine’s armed forces, tells us what motivated him to fight other people’s wars.
