Palestinian President Mahmoud Abbas has said that his people would "no longer accept" any peace plan proposed by the US following its decision to unilaterally recognise Jerusalem as the capital of Israel.

The Trump administration has been preparing a plan in secret, which is expected to be presented to the two sides in 2018.

"The United States has proven to be a dishonest mediator in the peace process and we will no longer accept any plan from the United States," Mr Abbas said after meeting French President Emmanuel Macron in Paris.

He also hit out at efforts by the US to intimidate countries ahead of a vote at the UN on Thursday, which saw 128 countries, including Ireland, condemn the US decision to recognise Jerusalem as the Israeli capital.

"I hope that the others will learn the lesson and understand that you cannot impose solutions by using money and trying to buy off countries," he added.

US Ambassador Nikki Haley, noting that Washington made "generous contributions" to the United Nations, had warned that the vote would affect "how Americans... look at countries who disrespect us in the UN".

Mr Macron repeated his earlier condemnations of the US decision on Jerusalem, but he also ruled out recognising Palestine as a state unilaterally, which France has mooted previously.

"The Americans have marginalised themselves and I am trying to not do the same thing," Mr Macron told the joint press conference with Abbas.

He added: "The solution will be built around two states so inevitably there will be a moment in the process when there is recognition. I want to do it at a moment that will help build peace on the ground."

Mr Macron has also ruled out launching a fresh French peace initiative in the short term, saying he is waiting to see what happens with the American effort, which Mr Abbas rejected on Friday.

The 40-year-old French leader has stepped up his meetings with leaders from the Middle East in recent weeks, hosting Israeli President Benjamin Netanyahu in Paris less than a fortnight ago.

Jordanian King Abdullah II visited yesterday and Mr Macron said he would visit the Palestinian territories in 2018.

"I have committed myself very clearly to doing everything" to further the peace process, Mr Macron said.

Mr Abbas praised Mr Macron's efforts as a mediator.

"We have trust in you. We respect the efforts made by you and we count heavily on your efforts," he said.

Elsewhere, the Minister for Agriculture and Food, Michael Creed, has said the Government is not worried about the threat by President Trump to cut financial aid to countries that go against its policy on Israel.

Ireland was one of many countries that voted at the UN General Assembly yesterday to reject Mr Trump's decision to recognise Jerusalem as Israel's capital.

Mr Creed said the vote was in line with Ireland's long-established position on Israel.

Separately, Israeli troops shot dead at least two Palestinians, according to a Gaza health official said.

The deaths happened as protests intensified against Washington’s recognition of Jerusalem as Israel’s capital.
