Israeli forces suppressed a weekly protest in Kafr Qaddum on Friday, which was attended by several Palestinian Authority officials.
Israeli forces fired tear gas, stun grenades and a liquid spray at protesters near Qalqiliya who were composed of international, Israeli and Palestinian activists.
An Israeli spokeswoman said 150 Palestinians had participated in a "violent and illegal riot during which they hurled rocks at security forces, who responded with riot dispersal means."
An Israeli border police officer was lightly injured by rocks, she added.
Fatah officials Mahmoud al-Aloul and Mahmoud Walweel attended as well as director general of the Nablus district Tayseer Nasrallah and Ghassan Daghlas, who monitors settler activity.
The world must hold Israeli responsible for its crimes against Palestinian civilians, al-Aloul said during a speech at the protest.
On Thursday, Israeli forces raided the village and detained 19 people suspected of participating in weekly protests in the village.
Among those arrested were two Palestinian Authority police officers.
