Rare Sumatran tigers born at Chester Zoo

A trio of rare Sumatran tiger cubs have been born at Chester Zoo.

The tigers, classed by conservationists as critically endangered, were born to eight-year-old tigress Kirana on 2 January after a 105-day pregnancy.

Sumatran tigers are only found in the wild in Sumatra, Indonesia. They are the smallest of all tigers and also have the narrowest stripes.

Tim Rowlands, curator of mammals at Chester Zoo, said he was "thrilled" with the "special arrivals".
