NABLUS (Ma'an) -- Settlers on Monday opened fire at Palestinians, injuring three, in As-Sawiya village south of the West Bank city of Nablus, a Palestinian Authority official said.

Dozens of residents of the illegal Yash Adam outpost attacked the village, PA settlement affairs official Ghassan Doughlas said.

Palestinian ambulances could not reach the village as settlers blocked the roads, Doughlas added.

The United Nations and several NGOs have warned of a recent surge in violent attacks by settlers against Palestinians.

The Israeli government dismantled an illegal outpost in Nablus on February 28, leading to a spree of attacks. According to the settlers' "price-tag" policy, Palestinians are made to pay for perceived anti-settler activity by Israeli authorities.

Settlers have firebombed a Palestinian home, damaged cars, uprooted trees, blocked roads and smashed shops since the demolitions in Havad Gilat. The PA issued a warning to Palestinians to avoid areas where settlers gather for their own safety.
