WATCH: State Department holds news briefing after Israelis and Palestinians killed in West Bank

State Department spokesperson Ned Price held a briefing on Monday after news of a Palestinian gunman shooting and killing an Israeli motorist in the occupied West Bank, the latest bloodshed in a fresh wave of fighting that shows no signs of slowing.

The killing occurred a day after two Israelis were killed by a Palestinian gunman in the northern West Bank, triggering a rampage in which Israeli settlers torched dozens of cars and homes in a Palestinian town. It was the worst such violence in decades.

The Israeli army said Monday’s attackers opened fire at an Israeli car near the Palestinian city of Jericho, hitting the motorist.

The assailants, traveling in one vehicle, then drove further and fired again, the army said. The attackers set their own vehicle afire and fled, setting off a manhunt.

The 27-year-old Israeli motorist was transferred from the scene to Hadassah Medical Center, where he later died of his injuries, according to a statement by hospital spokeswoman Hadar Elboim. The man was not immediately identified.

Earlier, Israel sent hundreds more troops to the northern West Bank to restore calm after Sunday’s violence.

Prime Minister Benjamin Netanyahu’s government, the most right-wing in Israel’s history, came under criticism for its failure to halt a surge in violence and for sending what some saw as mixed messages. As Netanyahu appealed for calm, a member of his ruling coalition praised the rampage as deterrence against Palestinian attacks.

The Israeli army also came under criticism for its failure to move quickly to stop the rioting, the worst such violence in decades.

“The government needs to decide what it is,” veteran columnist Nahum Barnea wrote in the Yediot Ahronot newspaper. “Is it resolved to enforce law and order on Arabs and Jews alike? Or is it a fig leaf for the hilltop youth, who do as they please in the territories? That same question also applies to the army, which has thus far failed to deal effectively with either Palestinian terrorism or Jewish terrorism.”

U.S. State Department spokesman Ned Price said the shooting attack and the rampage “underscore the imperative to immediately de-escalate tensions in words and deeds.”

The events also underscored the limitations of the traditional U.S. approach to the long-running Israeli-Palestinian conflict: Washington has been trying to prevent escalation while staying away from the politically costly task of pushing for a resolution of the core disputes.

As the violence raged in the West Bank, such an attempt at conflict management was taking place Sunday in Jordan, with the U.S. bringing together Israeli and Palestinian officials to work out a plan for de-escalation.
