An elephant calf that was separated from his herd in Malawi and raised by a human "mother" for months has died.

Jenny Webb, who raised the calf, said it died on Monday night "in her arms". She said the elephant had been sick with colic.

In February, Ms Webb adopted the elephant, which had been named Moses after being found in the grasses of a riverbed by game rangers at Vwazi Wildlife Reserve in northern Malawi.

She said rangers tried to find his family herd for two days without success and that his mother was likely killed by poachers.

Malawi's national parks did not have the funds to raise the little elephant so Ms Webb, the founder of the Jumbo Foundation, an orphanage for large animals, cared for him.
