Security forces arrested three Palestinians overnight Monday on suspicion they were involved in an incident that left a man seriously injured at the side of a road in the West Bank earlier in the day.
The three suspects were apprehended in the town of Kfar Qabalan, near Nablus, and handed over to the Shin Bet security services for questioning.
On Monday afternoon a man in his fifties was found unconscious at the Alon Junction in the northern West Bank with serious injuries including some to his head.
Magen David Adom emergency services resuscitated the man and transferred him to a hospital where he was still being treated on Tuesday.
An eyewitness said he was struck by a car, which drove off in the direction of Tapuah Junction.
Police and security forces began a search for the perpetrators. Investigators said it was not clear if the incident was criminally motivated or a terror attack and that all lines of investigation were being checked.
There have been a series of terror related hit-and-run incidents in Jerusalem and the West Bank by Palestinians over recent months, killing five Israelis and injuring over a dozen more.
