Prince Harry walks through minefield in Angola, continuing Diana's advocacy

Prince Harry on Wednesday walked through a minefield in Angola, harkening back to Princess Diana's historic land mine walk 28 years ago. 

The Duke of Sussex visited Angola in southern Africa with the HALO Trust organization, the same group his late mother worked with when she went to Angola in January 1997, seven months before she was killed in a car crash in Paris.

Diana's advocacy, along with images of her walking through a minefield, helped mobilize support for a land mine ban treaty that was ratified later that year.
