Mohammad Safa, Executive Director of PVA and its Main Representative to the United Nations, who has suspended his duties, accused the UN in a post on X of preparing for the possible use of nuclear weapons in Iran.
“I don’t think people understand the gravity of the situation as the UN is preparing for possible nuclear weapon use in Iran,” Safa wrote.
Referring to Tehran, he emphasized its population of nearly 10 million and warned of the human cost of any potential strike. In strongly worded remarks, he criticized those supporting military action and highlighted the presence of civilians, including families and children, in the city.
Safa further claimed, “I gave up my diplomatic career to leak this information. I suspended my duties so as not to be part of or a witness to this crime against humanity,” adding that his decision was aimed at preventing a potential “nuclear winter.”
He also urged global action, calling on people to “take the streets” and protest against any move toward nuclear conflict, while referencing recent large-scale demonstrations in the United States.
The remarks come days after his March 27, 2026 letter, in which he announced the suspension of all his duties as PVA’s Main Representative to the United Nations in New York, Geneva, and Vienna, as well as from UN committees and groups. In the letter, he cited alleged political pressure, misinformation campaigns, and ethical concerns related to conflicts in Gaza and Lebanon.
He further alleged that senior UN officials were failing to properly characterize these conflicts and claimed that dissenting voices were being silenced. Safa also said he had faced death threats, financial penalties, and censorship after expressing his views.
There has been no independent or official confirmation from the United Nations or other international authorities supporting Safa’s claims regarding nuclear preparations.
