The shooting on Saturday came amid a wave of Palestinian stabbings and attempted stabbings, car rammings and gun attacks that have killed about 25 Israelis, an American student and one Palestinian bystander 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 Israeli security forces in the West Bank, 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 a West Bank settlement on Jan. 17, and a pregnant woman was wounded in a separate attack in another settlement a day later. In both cases the suspects, who are both under arrest, were 15-year-old Palestinian boys.

Palestinian teenagers have carried out many of the stabbings or attempted stabbings, and in one case an assailant was as young as 12. In November, two cousins, ages 12 and 14, were arrested after they attacked an Israeli security guard on a light railway train in East Jerusalem, not far from their homes. In that case, relatives said the cousins had set out after watching video clips leaked from the interrogation of a 13-year-old Palestinian who was accused of participating in the stabbing of a 13-year-old Jewish boy and another Israeli civilian in East Jerusalem the month before.

The Palestinian authorities and local and international human rights groups have accused the Israeli police, the military and in some cases private security personnel and armed civilians of reacting with excessive force. Israel strongly rejects those accusations, saying that Israelis are acting legitimately in self-defense.

Sweden’s foreign minister, Margot Wallstrom, recently called for investigations into called “extrajudicial killings” of Palestinian attackers by Israeli forces. Israeli officials reacted furiously, saying that Ms. Wallstrom was no longer welcome in Israel, and Prime Minister Benjamin Netanyahu described her remarks as “outrageous,” “immoral” and “stupid.”
