The Kensington Palace Instagram account has posted images from Prince Harry's trip to South Africa earlier this year where he helped vets de-horn rhinos and protect elephants.
The photos reveal Harry's heartbreak at the suffering of rhinos, though one image shows the benefits of the work he and the vets are trying to achieve.
Another photo shows Harry almost eye-to-eye with a rhino. The caption reads "This was the second time Zawadi, a female black rhino, met someone from my family. My brother William fed her three years ago in Kent just before she left under a translocation project to Tanzania where she now lives in a sanctuary. Thanks to the passion and stubbornness of Tony Fitzjohn OBE and his amazing rangers, she and many others are living it up in the bush and their numbers are growing. She goes nuts for carrots and I loved being able to send William this photo."
