LONDON -- Newly released photos and video show Prince Harry helping to herd elephants in Africa during the summer.

The images released Friday show Harry working with conservationists in Malawi to help relocate roughly 500 elephants.

In the video, the prince says of the herding effort that it is the "most efficient and least invasive way of doing it."

He said that after three weeks of hands-on experience he is certain there is "zero stress" on the animals.

The images were released by the African Parks conservation group that manages protected areas and national parks on behalf of governments.

The photos show Harry and others helping to put the anesthetized animals onto trucks or into trailers so they can be driven away to a different wildlife reserve.
