Israeli settlers carried out attacks on a number of Palestinian villages across the occupied West Bank early Sunday, setting fire to two mosques and other properties.

Sunday’s attacks were spurred by clashes that erupted in the village of Tell, in the northern West Bank, where a crowd of Israeli settlers, some armed, approached the Palestinian village Friday.

Villagers came out to confront them, and a standoff followed, with video appearing to show one of the Palestinians grabbing a settler’s weapon. Palestinian authorities said the settlers provoked the violence, while the Israeli military said both sides fired shots. Four Palestinians and two Israelis were killed.
