"On 2nd anniversary of US 'ceasing participation' in the #JCPOA, I urged @antonioguterres to hold US accountable for violating its duties & forcing others to do so, too," Zarif tweeted on Saturday.
He further warned that "lawless bullying jeopardizes" the United Nations' credibility and poses a threat to international peace and security.
Earlier in the day, Iran’s ambassador to the United Nations said the US government’s unilateral policies and addiction to inhumane sanctions against other nations have undermined the credibility of the UN and the rule of law.
The US has endangered multilateralism across the world through its contemptuous treatment of international organizations and international law, Majid Takht Ravanchi said in an address to a virtual meeting of the UN Security Council, held on Friday to mark the 75th anniversary of the end of World War II in Europe.
The Iranian ambassador said the UN was established as a center to be used by countries to coordinate their attempts to resolve international problems, but the US and some countries have undermined the world body’s credibility through their contempt and contravention of the international law and resorting to inhumane measures such as sanctions, to which their foreign policy has become addicted.
