An Israeli police spokesman said an officer who had been near the scene opened fire after the attacker rammed his car into people by the roadside near the Israeli settlement of Elazar, close to the Palestinian city of Bethlehem.
Israel's Magen David Adom ambulance service said Nehum Nevis, 17, was unresponsive and "in severe condition with multi-system trauma," and that his 19-year-old sister Noam Nevis sustained moderate injuries.
Dozens of Israeli troops and medics were at the scene. The alleged attacker's vehicle, bearing Israeli license plates which allow greater freedom of movement in both Israel and the West Bank, was overturned by the roadside. Police said the attacker had been driving along a road which weaves past Palestinian towns and Israeli settlements.
