A Jordanian court on Sunday gave a reduced sentence to a 64-year-old man for killing his wife and two daughters last year over the woman's alleged “bad behaviour”, an official said.

“The court had initially sentenced him to life in prison, but it found mitigating factors and gave him instead a 15-year jail term,” the official said.

“The convict came home one night in March last year and saw a strange man secretly leaving the house. He got enraged and shot and killed his daughters and wife after she denied seeing any man.”

The official said the husband has told police he killed his wife because of her “bad behaviour”.

Murder is punishable by death in Jordan but in so-called “honour killings” courts can commute or reduce sentences, particularly if the victim's family or relatives agree to leniency.

Between 15 and 20 women are murdered in honour killings every year in Jordan, despite government efforts to curb such crimes.

Last month, a Jordanian court gave reduced sentences to a man convicted of stabbing to death his cousin for shunning his brother, and another for murdering his raped sister.

Another court in the Red Sea port of Aqaba jailed a man in January for two years for running over and killing his wife after “she threw a stone at him because he was upset that she bought a new car”.
