Monday's violence brought to eight the number of Palestinians killed by Israeli forces or armed settlers since Friday, as Palestinian authorities reported increased settler rampages across the West Bank.

Salah Bani Jaber, mayor of Aqraba, a town near the northern city of Nablus, witnessed Monday's settler attack. He told Reuters that some 50 settlers, many of them armed, attacked members of his community and fired at Palestinian youth, killing two of them and wounding others.

"There were Israeli soldiers at the scene who stood idly by watching the settlers," he said.

The Palestine Red Crescent Society said soldiers blocked its ambulances from reaching the area and tending to the wounded. The Israeli military said it was looking into the incident.

Earlier on Monday, Israeli forces raided Nablus, killing 17-year-old Yazan Ishtayeh and wounding three other people, the Palestinian Health Ministry said.

Over the weekend, hundreds of armed Jewish settlers raided Palestinian villages near the city of Ramallah, blocking roads, setting houses and cars ablaze, and firing at civilians, medics and civilians said.
