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 on Wednesday recreated his mother Princess Diana’s iconic 1997 walk through a landmine field in Angola. Wearing a flak jacket, he visited the minefield near Cuito Cuanavale to raise awareness about the ongoing landmine threat.

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.
