A Jordanian court sentenced a 61-year-old man to 10 years in prison on Wednesday after convicting him of killing his teenage daughter last year to "defend his honour", a judicial official said.

"In 2008, the 17-year-old girl was kidnapped and raped by a group of men, who are currently on trial," the official said.

"But the father suspected that his daughter was involved in a sexual relationship with one of the men. He shot her dead before handing himself in to police, claiming he wanted to defend his honour."

The court initially jailed the father for 15 years, "but decided to reduce the sentence after the man's family urged leniency", he said, adding the murder took place in Ein Basha, outside Amman.

In a separate case, a court commuted the death sentence of a man to 10 years in jail for strangling his married sister to death in 2007 "because he suspected the girl was involved in prostitution", in the Red Sea port of Aqaba, an official said.
