Approximately 80 international volunteers, including US Democratic congressional nominee Brad Lander, were detained by Israeli security forces near Nahalin in the occupied West Bank on October 21, 2026, while they were assisting Palestinian farmers with the olive harvest. Israeli lawyers consider this the largest mass detention of activists in the occupied West Bank in at least a decade.

This incident highlights the escalating tensions and violence in the West Bank during the critical olive harvest season, a period marked by increased risks for Palestinian farmers and international observers. The detention of a U.S. congressional nominee draws international attention to the challenging conditions and the efforts of human rights groups to provide a protective presence.

Detentions During Olive Harvest

On October 21, 2026, Israeli security forces detained approximately 80 volunteers from the United States, Israel, Britain, and Canada in the occupied West Bank, near Nahalin. The group included Brad Lander, the Democratic nominee for New York's 10th Congressional District, as well as rabbis from T'ruah, an American organization, and Rabbis for Human Rights, an Israeli group. These volunteers were providing a "protective presence" for Palestinian families harvesting olives in an area identified as a "hotspot community" due to risks during the harvest season. Some Palestinian families participating in the harvest had been unable to access their land since October 7, 2023.

Official Responses

The Israeli military stated that the area was a "closed military zone" and that the farmers and volunteers had not obtained prior approval for the harvest. The military asserted that such coordination is necessary for security and public order, viewing the arrival of dozens of activists as a provocation intended solely to undermine the harvesting process.

Brad Lander posted from a bus transporting detainees to a police station, stating, "I’ve been detained by the IDF, along with a group of rabbis & volunteers". He added, "We were simply harvesting olives in a grove near Nahalin in the West Bank. The occupation is a crime under international law. Harvesting olives isn't a crime under any law I know". Lander was later released with a "warning," which he attributed to his "public profile". He noted that he informed authorities he was "not even a congressmember yet, just a nominee". Despite his release, Lander emphasized that "several dozen rabbis & participants" remained in detention and called for their immediate release.

Context of Violence

This incident occurred during a harvest season described as the "most violent in recent history". There have been escalating Israeli settler violence and restricted Palestinian access to olive groves. Just days prior, on October 17, 2026, Israeli settlers reportedly assaulted European diplomats, including a French mayor, near the Palestinian village of Taybeh. Less than a week before the current detentions, Heidi Levine, an American photojournalist for The Washington Post, was reportedly attacked by settlers. The United Nations has observed that settler attacks in the preceding two weeks had already exceeded the total for the entire previous year's harvest season.

What We Could Not Confirm

The exact number of individuals who remained detained after Brad Lander's release could not be confirmed. The specific charges, if any, against those still held were not specified in the available records.
