The Iranian diplomat was planning to attend a meeting of the UN Security Council in New York.
The US refused to issue a visa to Iranian Foreign Minister Mohammad Javad Zarif, which would have allowed him to attend a meeting of the UN Security Council in New York on Thursday, a US representative said.
The statement by the American official, who spoke on condition of anonymity, came amid escalating tensions between the two countries after the US killed the most famous military commander in Iran, Qasem Suleimani, in Baghdad last Friday.
By the 1947 agreement on the location of the UN headquarters, the United States is generally required to allow access to this international organization to foreign diplomats. However, Washington says it can refuse to issue visas for reasons related to “security, terrorism, and foreign policy.”
The US State Department declined to comment.
A meeting of the Security Council on Iran would allow Zarif to be in the center of world attention and subject the US to public criticism for the murder of Suleimani.
