Motazz Obeidu, 32, was "seriously wounded by Israeli forces gunfire" in an arrest attack, the Ramallah-based Prisoners Club said on Thursday. Club’s director Amjad al-Najjar said Obeidu was "physically disabled".
Local residents said the arrest took place at Obeidu's shop in Al-Khalil.
Palestinian security sources said the Zionist forces arrested eight people in Burin village near the northern city of Nablus during an overnight raid.
It was not immediately clear why they had been arrested and there was no comment from the regime.
The incident came after the deaths of Palestinian inmates in Israeli jails, which has sparked an outrage among Palestinians and triggered street rallies and sit-in protests in solidarity with the prisoners.
