A mother who gave birth in a train toilet before hacking her baby son to death with a pair of scissors has been jailed for three years by judges in Russia.

Judges in Moscow heard how the healthy boy had been stabbed 44 times just moments after his birth.

The 25-year-old carried out the brutal slaying on a Lastochka intercity electric train, widely used across Russia.

The footage shows the mother telling the police how she carried out the killing. Further footage shows her in Moscow's Lefortovo Court during her trial.

She was found guilty of murdering her newborn boy eight months ago, in April.

Judges said they were taking into account the mother's emotional state when they sentenced her to three years behind bars.

Prosecutors said the judges were 'taking into account the gravity of the crime committed, as well as the personality of the defendant'.

Forensic medics told the court that the baby had been born perfectly healthy but died after he was stabbed 44 times.

The Moscow Interregional Transport Prosecutor's Office said in a statement on December 1: 'The Lefortovo District Court of Moscow sentenced a woman for killing a newborn on an electric train.

'She was found guilty of committing a crime under Art. 106 of the Criminal Code of the Russian Federation (murder of a newborn child by a mother).

'The court found that the 25-year-old woman, being pregnant, while in an electric train travelling along the Moscow Central Circle, independently gave birth to a viable child.

'Deciding to kill the newborn, she stabbed him 44 times.

'Taking into account the gravity of the crime committed, as well as the personality of the defendant, the court sentenced her to imprisonment for a period of three years to be served in a general regime colony.

'The state prosecution in the case was supported by the Assistant Southwestern Transportation Prosecutor.'
