Iran and Turkey lashed out at their regional rival, the United Arab Emirates on Friday over its decision to normalize diplomatic relations with Israel in a US-brokered deal.It accused the UAE of betraying the Palestinian cause.

The “Abraham Agreement” announced by United States President Donald Trump on Thursday, secures an Israeli commitment to halt further annexation of Palestinian lands in the occupied West Bank.

A joint statement released by US President Donald Trump, Israeli Prime Minister Benjamin Netanyahu and UAE leader Sheikh Mohamed bin Zayed al-Nahyan announced “the full normalization of relations between Israel and the United Arab Emirates”.

The UAE said the agreement also puts a hold on Israel’s plans to annex parts of the occupied West Bank, which the Palestinians view as the heartland of their future state.

The agreement makes the UAE the first Gulf Arab state — and the third Arab country, after Egypt and Jordan — to have full diplomatic ties with Israel.

The Palestinians said the deal amounts to “treason” and have called on Arab and Muslim countries to oppose it.

The Turkish foreign ministry said the United Arab Emirates had no authority to negotiate with Israel on behalf of the Palestinians or “to make concessions on matters vital to Palestine”. Turkey said the people of the region “will never forget and will never forgive this hypocritical behaviour” by the UAE.

Iran’s foreign ministry also slammed the accord, calling the deal a “dagger that was unjustly struck by the UAE in the backs of the Palestinian people and all Muslims”.
