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

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 paid powerful tribute to Princess Diana on Wednesday by returning to the area where she famously walked in 1997 to raise awareness about landmines. The area is still littered with deadly explosives from Angola's 27-year civil war, which ended in 2002.
