Israeli settlers descended on Palestinian olive harvesters and activists this week in the Israeli-occupied West Bank, beating them with clubs in an attack Palestinian health officials said sent at least one woman to the hospital with serious injuries. The attack Sunday in the town of Turmus Ayya, which was captured in videos obtained by The Associated Press, came as Palestinians say settler violence in the region is worsening. The United Nations and rights groups have raised the alarm as harvest season begins and Palestinian farmers are at growing risk while gathering olives. “Settler violence has skyrocketed in scale and frequency," Ajith Sunghay, the head of the U.N. Human Rights Office in the Palestinian territory, said in a statement released Tuesday.
