Scientists working to save the northern white rhino from extinction have produced two more embryos of the world’s most endangered mammal, increasing the number of viable embryos produced so far to five.

There are no known living males and neither of the two remaining northern white rhinos on Earth - a mother and her daughter living in Kenya - can carry a calf to term.
