The police identified Monday’s assailants as a Palestinian man and teenager, about 22 and 16. The older one, they said, was a resident of the Palestinian village of Beit Ur al-Tahta, near Beit Horon.

The two women were stabbed outside a grocery store in the settlement, according to the police. The assailants then headed for the store. Security camera footage appeared to show two men in dark hoodies trying to enter with knives in their hands as the store owner blocked them with a shopping cart. As they ran further into the settlement, a security guard shot and killed them.

About 25 Israelis, an American student and one Palestinian bystander have been killed in the attacks since Oct. 1. About 150 Palestinians have been killed during the same period. Up to two-thirds of them have been described by Israel as assailants. Others have been killed during protests and clashes with the Israeli security forces in the West Bank and East Jerusalem, and along Israel’s border with Gaza.

An Israeli mother of six, Dafna Meir, was stabbed to death in the doorway of her home in the settlement of Otniel on Jan. 17, and a pregnant woman was wounded in a separate attack in a secondhand clothing charity store in Tekoa, another settlement, a day later. In both cases the suspects, who are under arrest, are 15-year-old Palestinian boys. Israel’s Shin Bet security agency said the Otniel attacker told his interrogators that he had been influenced by Palestinian television broadcasts that cast Israel as “a killer of young Palestinians.”

Israel’s leaders attribute much of the violence to what they describe as incitement in the Palestinian news media and on social networks. Palestinians say the frustrations caused by the Israeli occupation are at the root of the outburst of violence.
