Israeli police said the three people killed in Sunday's shooting attack in the occupied West Bank were members of the police force.
"Three members of the police force were killed this morning in a shooting attack," Ouzi Levy, chief of the Israeli police in the West Bank, told reporters at the scene of the attack near the Tarqumiya checkpoint near the city of Hebron.
Israel's medical emergency service, Magen David Adom, earlier had announced the death of the three, two men and a woman.
"This was a very severe attack. We saw a vehicle with bullet marks on a mound beside the road," the emergency service said in a statement quoting two of its paramedics who had rushed to the scene.
Israel's far-right National Security Minister Itamar Ben Gvir also visited the scene of the attack and called for more checkpoints be set up in the area.
"Right to life (of Israelis) is more important than freedom of movement of PA (Palestinian Authority) residents," he told journalists.
"Instead of freeing terrorists, shoot them in the head."
Sunday's shooting comes as Israeli forces pressed on with a widespread operation in the West Bank since Wednesday.
Explosions and gunfire were heard in Jenin city on Sunday, an AFP photographer reported, as Israeli forces continued to operate there.
