The United Nations human rights office demanded on Tuesday that Israeli security forces immediately stop participating in and enabling continued attacks by Jewish settlers against Palestinians in the occupied West Bank, as the international communitys fears of a wider regional war continue to grow.

The remarks from Office of U.N. High Commissioner for Human Rights come in response to a recent settler rampage in several of the West Banks Palestinian towns. The latest wave of violence there was triggered by what Israeli authorities said was a militant attack on Friday that killed a 14-year-old Israeli boy from a settler family.

Neither Palestinians nor Israelis should take the law into their own hands to exact revenge, OHCHR spokesperson Ravina Shamdasani said during a press briefing in Geneva, calling the escalating violence in the West Bank a matter of grave concern.

According to the Palestinian Health Ministry, at least seven Palestinians have been killed either by Israeli security forces or by armed settlers since the attacks began Friday, with an additional 75 wounded.
