UN Deputy Spokesman Farhan Haq

The United Nations says the US must allow accredited Iranian diplomats to carry out their work freely, affirming the world body`s position that Washington, as host country, is obligated to permit the unrestricted movement of all UN-based diplomatic personnel.

UN Deputy Spokesman Farhan Haq made the remarks at a press briefing on Thursday when asked whether the world body had received a formal communication from the Islamic Republic regarding tightened restrictions on its Permanent Mission.

"Whenever countries have faced restrictions on their diplomatic personnel, they raise that with us, and then we remind the host country of its obligations under the Host Country Agreement to allow the free movement of diplomats accredited to the United Nations," he said.

Haq reiterated the organization`s "consistent stance," noting, "Our standpoint with all nations, not just Iran, is that we want to make sure that the host country allows their diplomats to go about their work freely, once they`ve been accredited here."

Tehran has sharply criticized the United States for escalating pressure on its UN Mission.

In a statement issued earlier in the day, the Foreign Ministry denounced Washington for abusing its "host-country status" by imposing extensive restrictions on the residence, movement, banking access, and even daily purchases of Iranian diplomats.

It said these measures had been designed to disrupt the normal and lawful functions of Iranian representatives.

According to the statement, Washington`s decision to bar three members of Iran`s UN Mission from continuing their work marked "the culmination" of US violations of the Host Country Agreement.

The ministry condemned the move as illegal, politically motivated, and a breach that raised questions about the United States suitability to host the UN Headquarters.

It warned that such actions undermined the UN`s effectiveness, damaged the credibility of the world body`s secretary-general, and violated the principles of the UN Charter.

The statement urged the UN chief to take action to prevent further infringements of the Islamic Republic`s diplomatic rights and cautioned against allowing the normalization of host-country violations.

Tehran emphasizes that it would continue seeking accountability from Washington and defending its sovereign rights under the Headquarters Agreement.

The latest dispute follows Iran`s earlier complaint in September, when its UN Ambassador Amir Saeid Iravani protested US-imposed movement restrictions on President Masoud Pezeshkian, Foreign Minister Abbas Araghchi, and other senior officials attending the 80th Session of the UN General Assembly.
