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.

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 traveled to Angola earlier this week and met the country’s president to discuss demining efforts, almost three decades after his mother’s memorable visit to the south African nation.
