Israeli security forces have demolished several illegal buildings in the West Bank settlement of Yitzhar, despite resistance from its hard-line Jewish residents.
Six border police officers were injured as hundreds of settlers threw rocks at the demolition workers.
According to an Israel Radio report security forces took down a number of buildings in the early stages of construction, along with two mobile homes.
In a statement the army said hundreds of settlers retaliated by throwing rocks, setting tyres on fire, blocking roads and damaging police vehicles. A nearby IDF post was also attacked.
