Israel revived plans on Wednesday to build 500 new homes for Jewish settlers in Israeli-annexed east Jerusalem, the first such move since the US presidential election

"The political significance of this action is that it is the first plan to be promoted since the US elections," Betty Herschman from the Ir Amim NGO said.

The plan for 500 housing units in Ramat Shlomo, an ultra-Orthodox Jewish neighbourhood in east Jerusalem of around 20,000, had been on hold since 2014, Ir Amim said. The Jerusalem municipality downplayed the significance of the new housing units, saying the plans were "not new and were approved years ago". Nevertheless, the announcement is likely to be interpreted by some as a first step in Israel expanding its settlements in the wake of Trump's upset election victory. Israeli right-wingers hailed his triumph as ushering in an administration far less critical of settlement expansion than that of outgoing President Barack Obama's.

The president-elect's adviser on Israel, David Friedman, told AFP last month that he does not believe Trump sees Jewish settlements in the occupied West Bank as illegal.

One Israeli minister said Trump's win meant "the era of a Palestinian state is over" while Meir Turjeman, chairman of the Jerusalem municipality planning committee, told public radio earlier in November that it meant suspended permits in east Jerusalem would be given the green light. He said the municipality intended to authorize thousands of housing units that had been frozen.

The international community considers all settlements illegal and sees them as one of the largest obstacles to peace between Israel and the Palestinians.

UN envoy Nickolay Mladenov told the Security Council on Wednesday that Israel's latest plan for new settlement homes in east Jerusalem was part of "increasingly worrying" developments and urged Israel to halt the construction.

"The situation on the ground is changing steadily, dangerously, as proponents of Israeli settlement expansion feel emboldened, internal divisions among Palestinians flare up, and the prospect of a future Palestinian state comes under threat like never before," Mladenov said.

Ahead of the Ramat Shlomo decision France said the planned constructions would be "illegal".

"The unabated continuation of the settlement policy only serves to increase tensions on the ground and undermines the prospects for achieving a just and lasting peace," its foreign ministry said Tuesday.

More than 200,000 Israelis now live in east Jerusalem, as part of a wider community of around 600,000 settlers in all the occupied Palestinian territories. The municipality did not respond Wednesday to the suggestion that the construction plans were related to events in the US.

Prime Minister Benjamin Netanyahu, whose government is considered the most right-wing in Israeli history, has so far been cautious in approving settlements.

Obama's administration has expressed mounting anger over Israeli settlement policy and speculation has grown that he could launch a final initiative before leaving. Obama has had frosty personal relations with Netanyahu throughout his two-term presidency.
