Manama: A court in Saudi Arabia has condemned a Saudi national to death for killing his wife and four children in 2013.

The multiple murders in Sharurah, a small town in the southern part of the kingdom, occurred at around 11.30pm.

The murderer himself reported the murders to the police, telling the officers that he had strangled them before stabbing them in the neck.

Reports said that the murderer decapitated his wife, 26, and then killed his three sons, aged between five and 11, and his two-year-old daughter.

Medical reports confirmed that the killer suffered from mental health problems.

Witnesses said he often mumbled incomprehensibly and that he was abusive and strict with his children.

They said his behaviour worsened a few days before he committed the crime.

On the day of the tragedy, he brought one of his children from the home of his former wife and killed him, according to Saudi reports.
