Two extremely rare white giraffes have been killed by poachers in north-eastern Kenya, conservationists say.

Rangers had found the carcasses of the female and her calf in a village in north-eastern Kenya's Garissa County.

A third white giraffe is still alive. It is thought to be the only remaining one in the world, the conservationists added.

Their white appearance is due to a rare condition called leucism, which causes skin cells to have no pigmentation.

News of the white giraffes spread across the world after they were photographed in 2017.

The manager of the Ishaqbini Hirola Community Conservancy, Mohammed Ahmednoor, said the two killed giraffes were last spotted more than three months ago.

"This is a very sad day for the community of Ijara and Kenya as a whole. We are the only community in the world who are custodians of the white giraffe," Mr Ahmednoor said in a statement.

"Its killing is a blow to the tremendous steps taken by the community to conserve rare and unique species and a wake-up call for continued support to conservation efforts," he added.

The poachers have not yet been identified, and their motive is still unclear.

The Kenya Wildlife Society, the main conservation body in the East African state, said it was investigating the killings.

What is leucism?

Leucism inhibits pigmentation in some skin cells

It is different to albinism where no melanin is produced at all

Animals with leucism may have darker pigment in their soft tissue

Giraffes with leucism retain their dark eyes, whereas animals with albinism have pink eyes

Birds, lions, fish, peacocks, penguins, eagles, hippos, moose and snakes have all displayed traits of leucism

The conservancy is in a vast unfenced area. There are also villages within the conservancy.

Some 40% of the giraffe population has disappeared in the last 30 years and poaching for meat and skin continues, according to the Africa Wildlife Foundation

The population went from around 155,000 in 1985 to 97,000 in 2015, according to the International Union for the Conservation of Nature (IUCN).
