Israeli Prime Minister Benjamin Netanyahu announced his intention on Tuesday to annex the Jordan Valley, a large swathe of the occupied West Bank if he wins a closely contested election just a week away, reports Reuters.
Palestinian chief peace negotiator Saeb Erekat called the planned move a war crime under international law governing the occupied territory. Israel captured the West Bank in a 1967 war and Palestinians seek to make the area part of a future state.
Israeli political commentators saw Netanyahu's declaration, in a speech broadcast live on Israel's main TV channels, as a bid to siphon support away from far-right rivals who have long advocated the annexation of Jewish settlements in the West Bank.
Netanyahu said in a speech broadcast live on Israeli TV channels, calling the area "Israel's eastern border".
Today, I announce my intention, after the establishment of a new government, to apply Israeli sovereignty to the Jordan Valley and the northern Dead Sea.
That step, he said, could be taken "immediately after the election if I receive a clear mandate to do so from you, the citizens of Israel".
Arab League foreign ministers condemned Netanyahu's plan, saying it would undermine any chance of progress towards Israeli-Palestinian peace.
Around 65,000 Palestinians and 11,000 Israeli settlers live in the Jordan Valley and northern Dead Sea area, according to the Israeli human rights group B'Tselem. The main Palestinian city is Jericho, with around 28 villages and smaller Bedouin communities.
Fighting for his political life after an inconclusive election in April, Netanyahu also reaffirmed a pledge to annex all of the settlements Israel has established in the territory. But he said that broader step could take longer and required "maximum coordination" with Washington, Israel's close ally.
He said, referring to a long-awaited blueprint from Washington for Israeli-Palestinian peace:
Out of respect for President Trump and great faith in our friendship, I will await applying sovereignty until the release of the president's political plan.
The US plan, Netanyahu reiterated, would likely be presented very soon after Israel goes to the polls on September 17. Netanyahu, head of the right-wing Likud party and in office for the past decade, failed to form a governing coalition following a national ballot in April.
"There is no change in the United States policy at this time," a Trump administration official said when asked whether the White House supported Netanyahu's move.
"We will release our Vision for Peace after the Israeli election and work to determine the best path forward to bring long-sought security, opportunity, and stability to the region."
White House senior adviser Jared Kushner said in early May that he hoped Israel would take a hard look at President Donald Trump's upcoming Middle East peace proposal before "proceeding with any plan" to annex West Bank settlements.
In an interview with the New York Times in June, US ambassador to Israel David Friedman said that "under certain circumstances" Israel has the "right to retain some, but unlikely all, of the West Bank".
