Israel views all of Jerusalem as its “eternal and indivisible capital”, but the Palestinians also want a capital there.

Israel intends to build 15,000 new settlement homes in East Jerusalem, the Housing Ministry said on Friday despite US President Donald Trump’s request to “hold back” on settlements as part of a possible new push for Israeli-Palestinian peace.

A formal announcement of the settlement plan, quickly condemned by the chief Palestinian negotiator, could come around the time Trump is scheduled to visit Israel next month.

Israel views all of Jerusalem as its “eternal and indivisible capital”, but the Palestinians also want a capital there. Most of the world considers Jerusalem’s status an issue that must be decided through negotiations. The last peace talks between Israel and the Palestinians collapsed in 2014.

Housing Minister Yoav Galant told Israel Radio that his ministry and the Jerusalem Municipality had been working on the plan for two years, with proposals for 25,000 units, 15,000 of which would be in East Jerusalem, which Israel captured in the 1967 Middle East war and later annexed.

“We will build 10,000 units in Jerusalem and some 15,000 within the (extended) municipal boundaries of Jerusalem. It will happen,” he said.

Saeb Erekat, the Palestinians’ chief negotiator, said Israel’s move was a systematic violation of international law and a “deliberate sabotage” of efforts to resume talks.

“All settlements in occupied Palestine are illegal under international law,” he said in a statement. “Palestine will continue to resort to international bodies to hold Israel, the occupation power, accountable for its grave violations of international law throughout occupied Palestine.”

Channel 2 news said an announcement on building could be made on “Jerusalem Day” which this year, according to the Hebrew calendar, falls on May 24, when Israel celebrates its capture of the eastern part of the city.

This year marks the 50th anniversary, with a large number of celebrations planned. Trump’s visit is expected to take place on or shortly after May 22.

Palestinians want East Jerusalem as the capital of a state they hope to establish in the occupied West Bank and the Hamas-ruled Gaza Strip. Trump told Reuters in an interview at the White House on Thursday that he wanted to see a peace deal.

“I want to see peace with Israel and the Palestinians,” he said. “There is no reason there’s not peace between Israel and the Palestinians – none whatsoever.”

The US leader met Israeli Prime Minister Benjamin Netanyahu in Washington in February and is to see Palestinian President Mahmoud Abbas at the White House on May 3.

In January, two days after Trump took office, Netanyahu said he was lifting restrictions on settlement construction in East Jerusalem, just as the city’s municipality approved building permits for hundreds of new homes.

During Barack Obama’s presidency, Netanyahu’s government came under repeated censure for building in settlements, which the previous US administration saw as an obstacle to peace. Under Trump, Netanyahu expected more of a green light to ramp up settlement building, but it hasn’t been straightforward.

While Trump has said he does not think settlements are necessarily an obstacle to peace, he did directly ask Netanyahu during a White House press conference in February to “hold back on settlements for a little bit”.

In 2010, Israel announced its intent to build homes in East Jerusalem during a visit by then-Vice President Joe Biden, who condemned the plan. It caused huge embarrassment to Netanyahu, who suspended the plan before reintroducing it in 2013.

Most countries consider settlement activity illegal and an obstacle to peace. Israel disagrees, citing biblical, historical and political connections to the land – many of which the Palestinians also claim – as well as security interests.

The East Jerusalem neighbourhoods where building is planned are Givat Hamatos, East Talpiot, Ramot, Pisgat Zeev, Neve Yaakov, Ramot Shlomo, Gilo and Atarot. These areas extend in an arc from north to south around the eastern side of Jerusalem, forming something of a buffer with the West Bank.
