A 26-year-old Jordanian was sentenced to life in prison on Sunday for killing his sister in 2010 after her husband accused her of adultery, a court official said.
"The criminal court initially condemned the man to death for stabbing to death his 28-year-old sister, but the sentence was immediately commuted to life in jail after their family urged leniency," he told AFP.
"The convict's 17-year-old bother took part in the crime, but he was not charged with anything because he suffers from behavioural disorder."
The official said the crime took place in Sahab, in the south of Amman.
"In 2008, the victim's husband filed a complaint against his wife, accusing her of adultery. This enraged her family, who threatened to kill her," he said.
"In July, 2010, the man sent his wife to her family after a fight. Her brother killed her immediately."
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 asks for leniency. Between 15 and 20 women died in such murders each year in the Arab kingdom, despite government efforts to curb such crimes.
