A woman in Iran claims to have given birth to a frog.

BBC Online says Iranian daily Etemaad claims the creature grew from larva inside the woman's body.

While the 'frog' has yet to undergo genetic tests, the paper quotes medical experts who say it has human characteristics.

Clinical biology expert Dr Aminifard said: "The similarities are in appearance, the shape of the fingers and the size and shape of the tongue."

The paper claims the mother-of-two, from the south-eastern city of Iranshahr, unwittingly picked up the larva when she swam in a dirty pool.

But it is unclear how this could have happened
