Prince Harry is in Angola on a visit for the 25th anniversary appeal of a mine clearance charity which was championed by his mother Diana, Princess of Wales.
The Prince is working on behalf of the HALO Trust, his spokesman said.
His late mother was passionate about its work in trying to rid mines and unexploded devices from war-torn lands.
His spokesman said: "Prince Harry, as patron of the HALO Trust's 25th Anniversary Appeal, is currently on a private visit to Angola to see HALO's mine clearance and will be touring minefields and meeting beneficiaries of HALO's work".
The late Princess Diana visited minefields being cleared by HALO in Angola just before her death in 1997 to help draw world attention to the horror of landmines.
The HALO Trust works with some of the world's most vulnerable people so they can plant their crops, rebuild their homes and raise their families in safety once the mines have been cleared.
Prince Harry has already visited minefields in Tete province in Mozambique in 2010 as part of his work with the project. He met amputees, seeing for himself the devastating impact that landmines have on some of the poorest people in mine-affected communities.
During his trip to Mozambique he spent time with a team of HALO deminers.
Under supervision, Prince Harry detonated several mines.
