Israel has widely deployed troops in the West Bank after clashes broke out on Friday across the occupied territory after the killing of an Israeli settler triggered violence that left two Israeli soldiers and four Palestinian villagers dead. “Israeli violence is spreading across the West Bank, fuelled by Israeli politicians openly calling for revenge,” said Yuli Novak, the group’s executive director. Later, army chief Eyal Zamir said he was sending more troops to the occupied West Bank. Five Palestinian villages surrounding Nablus were attacked by Israeli settlers on Friday, according to the Palestinian news agency WAFA. The towns and villages surrounding Nablus sit in one of the most violent parts of the Israeli-occupied West Bank.
