The condition of an Israeli citizen who suffered a severe head injury after Palestinians threw rocks at his vehicle overnight Saturday near Beit Ummar, north of Hebron in the West Bank, took a turn for the worse Monday, and doctors were concerned he may have sustained permanent brain damage.

Yeda’ayah Sharhaton, 25, was wounded while driving to his home in the West Bank settlement of Yatir, in the South Hebron Hills, after a large rock thrown by Palestinians shattered the windshield of his car and struck him directly in the face, according to Yedioth Ahronoth. Sharhaton, who was in the vehicle with his wife, Hadassah, and their one-year-old baby daughter, lost control of the car as a result of the attack, and it subsequently overturned, skidding into a ditch at the side of the road. Both Hadassah and the baby were lightly hurt.

A group of Palestinians from Beit Ummar who saw the crash rushed to the scene to help rescue the three Israelis from the overturned car. The group alerted IDF soldiers and called emergency medical services, who took the three Israelis to Hadassah Hospital in Ein Kerem in Jerusalem for further treatment.

Sharhaton was diagnosed with several fractures in his skull, a broken eye socket, a broken jaw, and internal bleeding in the brain. He initially managed to communicate with his wife via notes on paper, but has since been sedated.

Public figures in the settler community expressed outrage at the incident, urging the government to treat rock throwing as an act of terror and attempted murder.

“This is not for the first time it has been shown that rocks are just as dangerous as a rocket or bullet,” said Yohai Damri, the head of the Hebron Regional Council.

“I have the told army commanders that the IDF must ensure that every citizen have the ability to drive and arrive home safely, every terrorist who throws stones aimed at killing should know that he will be held accountable with his life,” he said.

Rock throwing by Palestinians all across the West Bank have become a serious hazard for drivers, both Israeli and Palestinian, and have on more than one occasion resulted in serious injuries or even death.

In March 2013, three-year-old Adele Bitton was critically injured when rocks were thrown at her mother’s car near the settlement of Ariel, causing a major accident.
