Prince Harry has followed in his late mother’s footsteps by wearing a flak jacket and walking down a path in an active land mine field in Angola to raise awareness for a charity’s work clearing explosives from old war zones. The Duke of Sussex is in the southern African country with the Halo Trust organization. It's the same group Princess Diana worked with when she went to Angola in January 1997. She was killed in a car crash in Paris seven months later. Diana’s advocacy and the images of her walking through a minefield helped mobilize support for a land mine ban treaty.
