Giant panda's twin surprise as second rare cub emerges at Vienna zoo

A giant panda that gave birth at Vienna's Schoenbrunn Zoo last week was hiding a tiny little secret - an extra cub.
The zoo originally announced the birth of one cub on August 7, but on Tuesday it said mother Yang Yang actually bore twins, her fourth and fifth cubs after Fu Long, Fu Hu and Fu Bao.
The fact that it took a while to discover the second cub is not surprising as the birth was observed by camera only.
And newborn pandas are tiny - the zoo said its latest addition was just 10cm (4in) long and weighed 100 grams (3.5 ounces).
The Schoenbrunn Zoo said no other European zoo has managed to breed giant pandas by natural means.
