An Israeli military spokeswoman said she was unaware of any detentions in Beita village, citing two in the Jenin and Qalqiliya areas.
Officials in Beita, south of Nablus, identified the detainees as Wadah Khaled Dweikat, 20, Jihad Dweikat, 19, and brothers Mujahed and Salah Rushdi.
The reports follow days of unrest following settler riots sparked by Monday's removal of several caravan homes erected near the Yitzar settlement. Riots saw settlers burn fields and vandalize cars, locals reported, with Israeli raids targeting Beit Furik on Tuesday.
