The United Nations has voiced grave concern over escalating violence in the West Bank, demanding that Israeli security forces “immediately” stop supporting settler attacks on Palestinians in the occupied territory.

The statement from the UN’s human rights office was issued hours after two Palestinian men were killed by Israeli settlers in a northern village south of Nablus, in the latest violent attack involving settlers in the increasingly tense West Bank, the Guardian reported. 

Monday’s violence brought to eight the number of Palestinians killed by Israeli forces or armed settlers since Friday, as Palestinian authorities reported an increasing number of attacks by settlers across the West Bank.
