HAWARA, West Bank >> Two Israelis were killed in a suspected Palestinian shooting attack on a car wash in a volatile stretch of the occupied West Bank on Saturday, the latest outburst of violence to rock the region.

The Israeli military said it was searching for suspects and setting up roadblocks near the town of Hawara, a flashpoint area in the northern West Bank, which has seen repeated attacks including one deadly shooting that triggered a rampage by Jewish West Bank settlers who torched Palestinian property.

Saturday’s shooting attack came after Palestinian medics reported that a 19-year-old Palestinian died of wounds sustained in an Israeli military raid into the West Bank on Wednesday.

The latest attack is part of a relentless spiral of violence that has fueled the worst fighting between Israel and the Palestinians in the West Bank in nearly two decades. Since spring last year, Israel has launched near-nightly raids in Palestinian towns in response to deadly Palestinian attacks.

Nearly 180 Palestinians have been killed since the start of this year and some 29 people have been killed by Palestinian attacks against Israelis during that time, according to a tally by The Associated Press. Israel says most of the Palestinians killed were militants. But stone throwing youths protesting the incursions and those not involved in the confrontations have also been killed.

Israeli paramedics said that when they arrived at the Hawara car wash, two Israeli males, aged 60 and 29, were found unconscious with gunshot wounds. Israeli media reported the two were father and son and identified them as Shay Silas Nigreka and his Aviad Nir from the southern Israeli city of Ashdod.

Underscoring the severity of the attack, the country’s military chief of staff, Lt. Gen. Herzi Halevi, visited the scene.

Prime Minister Benjamin Netanyahu sent his condolences to the family and vowed that the military would track down the shooter.
