United Nations Secretary-General Antonio Guterres is alleged to have sent a letter of congratulations to the Iranian regime on the Wednesday anniversary of the victory of the Islamic Revolution, according to a report from Iran's IRNA.
According to the state outlet, Guterres extended congratulations to Iranian President Masoud Pezeshkian, describing the day as an opportunity to reflect on the country's path, role, and contributions to the international community.
He also urged global cooperation to advance peace and security and uphold human rights.
UN Watch demanded that Guterres release the full text of his letter, stating that "the world deserves transparency on this matter."
"If the reports are authentic, we urge you to explain how congratulating a regime responsible for ongoing massacres serves the cause of peace and justice," a letter written by UN Watch to Guterres read.
Abbas Araghchi on list of invitees to speak at UN
The UN Watch also addressed the alleged scheduling of Iranian Foreign Minister Abbas Araghchi to speak before the UN Human Rights Council in two weeks.
Araghchi has been implicated in crimes against humanity, along with other members of the Iranian regime.
The letter called for Araghchi's invitation to address the UN be reversed, and threatened to urge Swiss authorities to arrest him if he did arrive in Geneva.
"The UN must not provide a stage for those who perpetrate atrocities against their own people and threaten global peace," the letter concluded.
