Two teenagers were seriously injured Friday afternoon in a ramming attack near the entrance to the Gush Etzion town of Elazar, Magen David Adom (MDA) reported.
Both victims were treated by MDA and have been transferred to Jerusalem hospitals.
The victims have been identified as 19-year-old Noam Nevies and her 17-year-old brother Nahum, from Gush Etzion.
Nahum sustained an injury to his head and is in serious condition, unconscious and on a respirator, while his sister Noam was moderately injured.
Dr. Bala Miklush, who heads Hadassah Ein Kerem's Trauma Department, said: "We received the young man of 17, who was sedated and on a respirator. Initial examinations showed that he had suffered a head injury. He is not yet out of danger. He is currently being operated on by our surgical staff. He has a severe brain hemorrhage."
Professor Yoram Weiss, Medical Director at Hadassah Ein Kerem Hospital, described Nahum's injuries as "very serious."
"He has a brain injury and a fracture in his skull," Prof. Weiss said. "His life is in danger."
Noam is currently hospitalized in the trauma department at Shaare Zedek Medical Center.
Shaare Zedek Director-General Ofer Merin said: "A young woman of about 20 arrived here after being injured in a ramming attack. She arrived generally in good condition, fully conscious and with injuries we are used to seeing from ramming attacks, mostly abrasions and injuries to her limbs. Her condition is light to moderate, and she will require hospitalization."
The public is asked to pray for Nahum Elimelech ben (son of -ed.) Zahava Rivka, and Noam bat (daughter of - ed.) Zahava Rivka.
The terrorist has been neutralized.
MDA paramedic Lior Levi said: "When we arrived at the scene we saw a 17-year-old boy and a 19-year-old youth in the ditch behind the bus stop. The boy was unresponsive and suffered a head injury as well as injuries to multiple bodily systems, and the girl was partially conscious."
"We administered lifesaving medical treatment, including sedating the boy and placing him on a respirator, and transferred them urgently to hospitals, with the boy in serious condition and the girl in moderate to serious condition."
An IDF statement read: "Following the report regarding a car-ramming attack adjacent to the community of Elazar, southwest of Bethlehem, an initial inquiry into the incident indicates that a terrorist ran over two civilians. The civilians were injured and evacuated to a hospital for medical treatment. The terrorist was neutralized. IDF troops are at the scene."
Judea and Samaria Police said that a police officer who noticed a vehicle driving quickly towards a bus stop and injuring two young people standing there, shot at the driver when he attempted to exit his vehicle, effectively neutralizing him.
Gush Etzion Regional Council Head Shlomo Ne'eman responded: "Unfortunately we are experiencing a lack of deterrence that's affecting residents of Gush Etzion in particular and Judea and Samaria in general."
"We demand from the government action that will lead to the end of this uncertainty for the future of Judea and Samaria. We are calling for the establishment of sovereignty and the answer is to continue to build and grow in Judea and Samaria.
"To the terrorists we say - you have no chance, and you have no future. We have faith that the IDF and security forces in the area will do everything possible to restore security to the Gush/Hevron area quickly. We wish those injured a speedy recovery and wish their families well."
