US Ambassador to the UN Nikki Haley told the Security Council on Tuesday that the US remains committed to mediating peace talks between Israel and the Palestinians, but stressed that the decision to move its embassy to Jerusalem ‘will not change.’

Watch: Haley’s address to the UN Security Council

In a fiery address to the UN Security Council on Tuesday, US Ambassador to the UN Nikki Haley slammed the Palestinian Authority for its refusal to negotiate with Israel under US mediation.

“The Palestinian leadership has a choice to make between two different paths,” Haley said. “There’s the path of absolutist demands, hateful rhetoric and incitement to violence; … or, there’s the path of negotiation and compromise.”

“The United States stands ready to work with the Palestinian leadership, … but we will not chase after you,” she added, addressing an absent Palestinian Authority leader Mahmoud Abbas, who had chosen to leave the meeting after making his statement.

Haley called the UN “a biased organization when it comes to Israel,” and held Hamas accountable for the suffering of Gazans. “The people of Gaza live in truly awful conditions, while their Hamas rulers put their resources into building terror tunnels and rockets,” she said.

Haley also said the Obama administration had made “a serious error” when it did not veto UN Resolution 2334 against the Israeli settlements, effectively allowing it to pass. That resolution, she said, “encouraged the false notion that Israel can be pushed into a deal that undermines its vital interests.”
