WASHINGTON/ANKARA

U.S. Ambassador to the UN Nikki Haley has warned member states ahead of a voting on a resolution calling for the reversal of President Donald Trump's decision on Jerusalem, according to a report by Foreign Policy.

On Thursday, the UN General Assembly will hold a rare emergency special session regarding Trump's Dec. 6 decision to recognize Jerusalem as Israel's capital and relocate Washington’s embassy from Tel Aviv to Jerusalem.

Citing an email, the news magazine reported Tuesday that Haley warned the member states, saying President Trump was "watching" the voting.

"As you consider your vote, I want you to know that the President and U.S. take this vote personally.

"The President will be watching this vote carefully and has requested I report back on those countries who voted against us. We will take note of each and every vote on this issue," Haley wrote in the email, Foreign Policy said.

On Tuesday, Haley posted on Twitter, saying: "At the UN we're always asked to do more & give more."

"So, when we make a decision, at the will of the American ppl [people], abt [about] where to locate OUR embassy, we don't expect those we've helped to target us. On Thursday there'll be a vote criticizing our choice. The US will be taking names," she said on Twitter.

Jerusalem's status has long been considered a final status issue to be determined by Israeli-Palestinian peace negotiations and Trump's decision is widely seen as undercutting that long-standing understanding. East Jerusalem, which Palestinians are seeking to make the capital of their state, has been under Israeli occupation since 1967.
