Chimpanzee looks after tiger cubs in Thai zoo

A young chimpanzee has become the unlikely substitute mother for a group of tiger cubs in a Thai zoo.

Dodo, the two-and-a-half-year-old chimpanzee, was trained to feed the cubs from a bottle of milk, and has been doing the job for about a year.

But keepers say the cubs will soon outgrow Dodo and they will have to be separated.
