The Kruger National Park in South Africa is where most of the country's rhino are being slaughtered. Authorities are battling to protect the species from poaching gangs.
Scientists working to resurrect the near-extinct northern white rhinoceros said on Thursday that they would no longer be collecting eggs from one of the two surviving living individuals in an extraordinary breeding experiment.
Citing risk and safety reasons, scientific consortium Biorescue said it had decided to retire the older of the two females, 32-year-old Najin, as a donor of egg cells for the ambitious project.
