A new Israeli settlement planned for construction in the occupied West Bank will encroach on Palestinian land recognized by UNESCO as a World Heritage site, Israeli peace activists say.

Much of the international community views Israeli settlements in the West Bank as illegal, and many were established illegally under Israeli law, but tolerated by the government.

Bezalel Smotrich, the far-right finance minister and a settler himself, gave preliminary approval to the new settlement, Nahal Heletz, in June, and the country’s planning authorities signed off on it on Wednesday.

But the area designated for the settlement was much bigger than what was shown in a plan the government published in July, according to an Israeli advocacy group, Peace Now, which closely tracks settlements. The new plan claims over 150 acres rather than the 30 acres announced previously, and all of it is on UNESCO-designated territory, the group said.

Mr. Smotrich, who is part of Prime Minister Benjamin Netanyahu’s governing coalition, has pushed for measures that would expand Israeli settlements in the West Bank in exchange for the release of funds withheld from the Palestinian Authority, which partly administers the territory.

Peace Now accused Mr. Smotrich of disregarding the UNESCO Convention in a statement on Wednesday. Israel is a party to the World Heritage Convention, though it left UNESCO in 2019, accusing the multilateral organization of trying to minimize Jewish ties to the land of Israel. It also objected to the organization’s acceptance of Palestine as a member state in 2011.
