Four children, aged between four months and nine years, were in the car during the attack and were lightly wounded.
“Palestinian terrorists opened fire on an Israeli family car, killing both parents,” said Ofir Gendelman, a spokesperson for Prime Minister Benjamin Netanyahu.
“Luckily, their four kids, now orphans, were unharmed.”
The Palestinian group Hamas praised the attack as a “heroic operation carried out by resistance fighters in the West Bank”.
The attack comes as tensions continue to flare between Israelis and Palestinians over the al-Aqsa Mosque compound in occupied East Jerusalem.
Over the past two weeks, Palestinian protesters have clashed with Israeli police at the hilltop compound and unrest has spilled over to Arab neighbourhoods of East Jerusalem and the West Bank.
