The UN Security Council will hold an emergency meeting Wednesday to discuss Israeli plans to build more Jewish settlements in occupied Arab east Jerusalem, diplomats said.
The urgent talks were requested by Jordan following a letter from Palestinian envoy Riyad Mansour, who called on the 15-member council to "address this crisis situation in occupied east Jerusalem."
Israeli occupation authorities pledged to build more than 1,000 new settler homes in east Jerusalem on Monday, angering Palestinians who warned it could trigger an "explosion" of violence.
In his letter, the Palestinian representative said the council should demand that the occupation authorities rescind its plan immediately and "commit to the path of peace that it has clearly and recklessly abandoned."
The meeting beginning at 1900 GMT was not expected to yield a resolution and it was unclear if the council would issue a statement following its discussions.
US State Department spokeswoman Jen Psaki declined to say whether Washington would oppose any Security Council action that was critical of Israel.
"We don't have information yet on what the plan is," she said.
On Tuesday, Israeli Prime Minister Benjamin Netanyahu hit back at US and European criticism, saying the statements were "detached from reality."
The European Union said the plans "call once again into serious question Israel's commitment to a negotiated solution with the Palestinians," warning of consequences for EU-Israel ties.
Washington said it was "deeply concerned" by the prospect of more settlements, adding that "moving forward with this type of action would be incompatible with the pursuit of peace."
But Netanyahu insisted Israel would not change course.
"We will continue to build in Jerusalem, our eternal capital," he said.
UN Secretary General Ban Ki-moon last week urged Israel and the Palestinians to move away from unilateral actions that stoke tensions and work toward restarting peace talks.
"International law is clear: settlement activity is illegal. It runs totally counter to the pursuit of a two-state solution," Ban said.
UN diplomats say the Israeli push to build more settlements is imperiling the two-state solution and dimming prospects for Palestinian statehood on land that is riddled with Jewish settlements.
The council meeting on the Israeli actions comes as the Palestinians are pushing for a UN resolution setting 2016 as the date for the end of Israeli occupation.
Tensions between Israel and the Palestinians have also risen over Jewish visits to the Al-Aqsa mosque compound, Islam's third holiest shrine.
Jerusalem's Israeli mayor visited the Al-Aqsa mosque compound Tuesday, angering Islamic authorities, but police said the day passed in "relative calm" after weeks of tension at the flashpoint shrine.
UN Under-Secretary General for Political Affairs Jeffrey Feltman is expected to brief the council at the meeting on Wednesday.
