Israeli emergency medical services say three Israelis have been injured after a Palestinian driver rammed into them near the West Bank settlement of Beit Arieh.
Emergency services spokesman Yonatan Yagodovsky said on Thursday that one Israeli was badly injured in the attack.
It's the latest incident in nearly three months of Palestinian shootings, stabbings and attacks using cars.
Police spokeswoman Luba Samri says Israeli forces are searching for the attacker, who escaped into the nearby Palestinian village of Luban. The village is close to the border between Israel and the West Bank.
Since mid-September, 19 Israelis have been killed in Palestinian attacks. At least 109 Palestinians have died in the latest wave of violence, of whom 74 are said by Israel to be attackers.
