Western leaders and veterans of the Second World War are in northern France to mark 80 years since the D-Day landings -- the start of the operation to liberate northern Europe from the Nazis. We hear from the ceremonies, and from some of the survivors.

Also in the programme: more than forty people have been killed in an Israeli airstrike on a UN-run school that was sheltering displaced families – we hear from UNRWA and the Israeli Defence Forces; and we talk to one of the scientists who have discovered a new way to predict dementia, many years before symptoms appear.
