An Arab diplomat says ambassadors from the UAE, Bahrain and Oman who attended the unveiling ceremony of a contentious US-devised Middle East proposal were not briefed on the details of the scheme.

The unnamed diplomat told Israel�s Haaretz newspaper on Saturday that Washington did not disclose the full details of its so-called peace plan to the three Persian Gulf Arab states ahead of its release, but only presented them with a vague outline of the initiative.

Trump unveiled his self-proclaimed deal of the century during an event at the White House alongside Israeli prime minister Netanyahu in Washington on Tuesday.

The only Arab ambassadors present were from the UAE, Bahrain and Oman -all members of the Arab League that are also among Washington�s closest allies in the region.

The diplomat said the White House had urged those Arab countries to attend the event, sending them a document of general statements about a Palestinian state and a capital in East Jerusalem al-Quds.

However, he added, when they got into the minute details of the plan, we understood that there is no Palestinian state in practice and there is no capital in East al-Quds, and more importantly, that there is an attempt to divide al-Aqsa Mosque.

The Arab diplomat said the disappointment with the details of the US plan led the three Persian Gulf countries to join the other Arab League member states in voting to reject the US scheme.

These are clauses that no Arab or Islamic countries can agree to, he said, and so ultimately all the foreign ministers fell in line with the position opposing the Trump plan.

In a statement on Saturday, the Arab League said it rejects the US-Israeli �deal of the century� considering that it does not meet the minimum rights and aspirations of Palestinian people.

The 22-member pan-Arab body further agreed not to ... cooperate with the US administration to implement this plan, insisting on a solution that includes a Palestinian state based on the 1967 boundaries, with East Jerusalem al-Quds as its capital.

All Palestinian groups have unanimously rejected Trump�s initiative that largely meets Israel�s demands in the decades-old conflict while creating a Palestinian state with limited control over its own security and borders.

It enshrines Jerusalem al-Quds as Israel�s undivided capital and allows the regime to annex settlements in the occupied West Bank and the Jordan Valley.

The plan also denies the right of return of Palestinian refugees into their homeland, among other controversial terms.

Israel calls off West Bank annexation meeting

After the unveiling of the US Mideast deal, unnamed Israeli officials said Netanyahu would convene a cabinet meeting on Sunday to seek approval to annex parts of the occupied West Bank.

But an official at Netanyahu�s office said on Saturday that there would be no meeting, declining to comment further.

The retreat came, the report said, after Britain cautioned Israel against advancing the West Bank annexation.

Any such unilateral moves would be damaging to renewed efforts to re-start peace negotiations, and contrary to international law, the UK Foreign Office said in a statement.

Any changes to the status quo cannot be taken forward without an agreement negotiated by the parties themselves.

Israel strikes Gaza, suspends cement imports

In another development on Saturday night, Israeli warplanes attacked targets in the northern Gaza Strip, claiming that they came in retaliation for the launch of rockets and incendiary balloons from the blockaded coastal enclave.

Additionally, the Israeli military and the so-called coordinator of government activities in the occupied territories announced an embargo on bringing cement into Gaza.

The Israeli military further cut 500 permits into the occupied territories for Gaza merchants effective Sunday morning until further notice.
