The Palestinian ambassador in London, Husam Zomlot, warned the British government that any decision to move the British embassy from Tel Aviv to Jerusalem would constitute a flagrant violation of international law.
And Downing Street announced in a statement that Prime Minister Liz Truss informed her Israeli counterpart Yair Lapid last Wednesday - during a meeting in New York on the sidelines of the United Nations General Assembly - of her intention to "reconsider the current headquarters of the British Embassy in Israel."
Yesterday, Thursday, Lapid said - in a tweet on Twitter - "I thank my dear friend, British Prime Minister Liz Truss, who announced that she is thinking positively of moving the British embassy to Jerusalem."
Lapid's tweet and the Downing Street statement aroused strong discontent on the Palestinian side.
"It is extremely regrettable that Prime Minister Truss, in her first appearance at the United Nations, has vowed to violate international law by promising to review the location of the British Embassy in Israel," Ambassador Hossam Zomlot said in a tweet on Twitter.
"Any move of the embassy would be a flagrant violation of international law and the UK's historical responsibilities," he added.
The Palestinian diplomat warned that moving the embassy from Tel Aviv to Jerusalem "would undermine the two-state solution and fuel an already fragile situation in Jerusalem and the rest of the occupied territories."
Zomlot considered that "such a promise is immoral, illegal and irresponsible."
Trass had made a pledge during her tenure of foreign affairs to review the embassy's website, in a letter to the "Friends of Israel" from the Conservative Party during her competition for the party's leadership.
And if Trass goes ahead with its plan, it will have followed in the footsteps of former US President Donald Trump, who in 2018 issued a controversial decision to move his country's embassy from Tel Aviv to Jerusalem.
On that day, Trump recognized Jerusalem as the capital of Israel, in an unprecedented move that angered the Palestinians, who are looking to make the eastern part of the holy city the capital of their promised state.
The vast majority of countries refrain from moving their embassies from Tel Aviv to Jerusalem, as they do not recognize the legitimacy of the Israeli occupation of the eastern part of the city.
Israel occupied East Jerusalem and the West Bank in 1967, and later announced the annexation of the eastern part of the holy city, in a decision that was met with widespread international rejection.
