Iravani made the comments on Wednesday as he addressed a UN General Assembly meeting on the "Use of Veto".

The meeting was held nearly two weeks after the US vetoed a UN Security Council resolution that would have granted Palestine full membership at the world body.

Here is the full text of the Iranian envoy’s speech during the Wednesday meeting.   

Mr. President,

At the outset, I would like to express my gratitude to you for organizing this meeting.

We also express our gratitude to Algeria for its dedicated efforts in support of Palestine in the Security Council and for spearheading the draft resolution put forward to the Security Council, recommending the endorsement of Palestine's full membership in the United Nations.

Our heartfelt appreciation also extends to the Council members who demonstrated solidarity with the Palestinian cause by voting in favor and supporting Palestine's full membership.

Mr. President,

The Islamic Republic of Iran supports Palestine's request for full membership. We believe that the admission of Palestine as a full member of the UN marks a pivotal moment in addressing the historical injustices endured by the Palestinian people. However, we deeply regret yet another irresponsible action by the United States, a permanent member of the Security Council, in using veto to block such a legitimate right of the Palestinians.  

This shameful veto demonstrates once again that the US remains the sole impediment hindering the realization of the noble aspiration of the Palestinian people for full membership. This veto was also made against the collective will of the international community.

It is regretful that the US blatantly challenged Palestine’s eligibility for membership in the United Nations and implied that there remains a question as to whether Palestine is peace-loving; it is entirely an outrageous argument.

The United States, as a staunch supporter of the occupying regime, is the main cause of the UN’s failures, especially within the Security Council, in upholding the legitimate rights of the Palestinians.

Despite the US cynical efforts, the voting results of the Security Council speak loudly and display how the United States remains isolated in the United Nations and how the international community stands united in support of the rights of the Palestinian people.
