Palestinians in Bethlehem were burning photos of President Trump on Tuesday night – ahead of a pending announcement to declare Jerusalem as the capital of Israel and possible moving of the US Embassy from Tel Aviv.

The White House says President Donald Trump will deliver remarks Wednesday outlining his decision on a potential move of the U.S. Embassy in Israel.

White House spokeswoman Sarah Huckabee Sanders says the president is “pretty solid” in his thinking on the plan but won’t say what Trump will announce. Sanders says the president will make the “best decision for the United States.”

The move to declare Jerusalem Israel’s capital could inflame tensions across the Middle East, but will offset a likely decision delaying Trump’s campaign promise to move the U.S. Embassy from Tel Aviv to Jerusalem.

Trump has discussed “potential decisions regarding Jerusalem” during calls with leaders of Israel, the Palestinian Authority and Jordan.

A White House statement on the Tuesday calls says Trump also “reaffirmed his commitment to advancing Israeli-Palestinian peace talks.”

The statement does not say if Trump discussed whether the U.S. will recognize Jerusalem as Israel’s capital, or move the U.S. Embassy from Tel Aviv to the contested city.

Statements from the offices of Palestinian President Mahmoud Abbas and Jordan’s King Abdullah II said Trump indicated plans to move the embassy in the calls. It was unclear if he outlined when he would take such a step.

Both leaders warned Trump that moving the embassy would threaten Mideast peace efforts.
