An Israeli man was wounded in a stabbing attack on Highway 5, near the West Bank settlement of Ariel, on Sunday afternoon.
The victim, 25, sustained moderate to serious knife wounds to his upper body.
The assailant fled the scene. A suspect was apprehended by security forces a few hours later.
The Shin Bet identified the suspect as Tamer Khadir, 26, a resident of Beita, a Palestinian village located near Nablus. He does not have a record with the security forces.
Earlier Sunday, an Israeli was moderately wounded in a stabbing attack at the Metzad Junction in the West Bank. The assailant, a Palestinian, escaped, and Israeli troops are searching for him.
Meanwhile, a stabbing attack was thwarted near the Tomb of the Patriarchs in Hebron, when security forces shot a knife-wielding Palestinian woman.
