RTÉ presenter Joe Duffy has written a new book with Freya McClements called Children of the Troubles: The Untold Story of the Children Killed in the Northern Ireland Conflict.

It follows on from his previous book about the children killed during the 1916 Easter Rising.

At least 3,700 people lost their lives during the Troubles, and 186 children were identified for the book.

Joe and Freya joined us on The Last Word to discuss the stories of these lost children.
