Harry walked through a minefield in Angola, retracing a journey by his mother, Diana, Princess of Wales, in 1997. Several countries plan to revive use of the weapons.

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.

Prince Harry visited Angola in southern Africa with the HALO Trust organization, the same group Princess Diana worked with 28 years ago.
