Zoo penguins massacred by fox

Penguins have been massacred by a fox that found its way into the National Zoo and Aquarium.

The Canberra zoo's director Trent Russell said the fox entered the zoo over the weekend and took several of the Little Penguins.

The penguin exhibit has been temporarily closed.

Visitors to the zoo have been asked not to question staff and volunteers about the attack, as they have found it very upsetting.

"Many of them would find this difficult to talk about," Mr Russell said in a statement.
