Munther Khader Al-Omor, 20, was detained in an army raid on his home in al-Tuwani village, prompting clashes between residents and soldiers, popular committee coordinator Rateb al-Jabour told Ma’an.
An Israeli military spokeswoman said she was not aware of the incident. She said three people were detained overnight in Rakhme, near Bethlehem, three from Beit Awwa, west of Hebron, and others in Silwad and Hizma, near Ramallah.
Separately, locals said 13 sheep in south Hebron village Susiya were killed on Friday after settlers sprayed toxic substances on plants in their grazing area.
Herdsman Jihad al-Nawajah told Ma’an plant samples were taken to a laboratory in nearby town Yatta and found to be contaminated with poisonous chemicals.
Al-Jabour condemned Israeli policies in the area, which he said aim to displace Palestinians from their land.
The Israeli government has ordered demolition of eight of the 12 villages in an area south of al-Tuwani that the army designates as a military training zone.
