The Military Advocate General charged on Thursday the mother of the 19-year-old Palestinian man who stabbed three Israelis to death at their Shabbat table Friday night with incitement. The indictment said that the mother, Abtisam al-Jalil, gave an interview the day after the attack in which she praised her son's actions.

Her son, Omar al-Abed from the West Bank village of Khobar, infiltrated a house in the nearby settlement of Halamish and murdered Yosef Salomon, 70, and his adult children, Chaya, a 46-year-old teacher, and Elad, 36. He also wounded Yosef's wife Tova, 68, who survived. He was stopped by a neighbor of the Salomons, an off-duty soldier, who heard the shouting, rushed over to the house and shot him.

In a video shared on Palestinian media, Jalil said, "I am proud of my son, whom God will protect and release and take care of." She said that when the Israeli army entered her home after the attack, the soldiers said that she had encouraged her son to carry out the attack, which she denied.

The army arrested Jalil on Tuesday. Abed's father was quoted in Israeli media as saying he was opposed to any attack and that he would have stopped his son had he known of his murderous intentions.

The assailant is believed to have acted alone. He had posted a message on Facebook hinting at his plan about an hour and a half before the attack, saying that he was "going to die for Al-Aqsa."

Thursday evening, Prime Minister Benjamin Netanyahu told the Salomon family that he supported executing their family's attacker.
