Austrian man Josef Fritzl, who held his daughter captive in a cellar for 24 years, has been charged with murdering one of the children he had with her.

Prosecutors allege he was responsible for the death of a new-born in 1996 by failing to seek help even though he was aware that the baby might die.

If proved, the charge could carry a sentence of life imprisonment.

The 73-year-old had told police that the child, one of twins, had been born dead and he had burned the body in a stove.

Elisabeth, 42, gave birth to seven children during her captivity, three of whom remained with her in the cellar, never seeing daylight, while three more were brought up in Mr Fritzl's family with his wife.

Mr Fritzl has also been charged with rape and sequestration, which carry a maximum sentence of 15 years in jail.
