FILE - In this Jan. 15, 1997 file photo, Britain's Princess Diana uses a remote switch to trigger the detonation of some explosive ordinance dug up by mine sweepers in Huambo, Angola. Prince Harry is offering his support to Angola's new 47 million pound ($60 million) initiative to clear land-mines, saying it will protect lives and help communities through conservation-led development. Speaking Monday, June 17, 2019 at the Chatham House think tank, Harry picked up the mantle for a cause near to the heart of his mother, the late Princess Diana, who worked with the Halo Trust on de-mining issues.
