A Jordanian judicial official says the country's state prosecutor has charged a man with premeditated murder who is suspected of drowning his 22-year-old sister for having an extramarital affair.

The official says the unidentified woman's brother beat her with the help of his family Saturday and then took her to the Dead Sea, where he drowned her.

The official says the state prosecutor also charged the woman's parents and another brother Monday with assisting in the murder by knowing about it and for beating the woman before she died. He says they carried out their suspected actions after seeing an unidentified man leaving the slain woman's house.

The official spoke on condition of anonymity Monday because he was not authorized to talk to the media.
