Referring to the deal struck with the help of Pakistani mediation, Tehran’s UN ambassador said in remarks in New York on Friday, “that if the United States continues to violate its obligations under the Islamabad Understanding, Iran will no longer consider itself bound by its commitments under that understanding”, according to a statement carried by state broadcaster IRIB.

The Iran-US deal was preceded by an April ceasefire, but the two sides have exchanged significant fire in recent days over the Strait of Hormuz, threatening talks laid out under the deal aimed at finding a permanent resolution to the war.

Following the exchanges, US President Donald Trump declared the ceasefire over, but said talks with Iran would continue.

In his remarks to reporters on Friday, Iranian UN representative Amir Saeid Iravani said Washington had “violated its obligation by launching and continuing large-scale military attacks against Iran’s sovereignty and territorial integrity”.

“Iran remains committed to the faithful implementation of (the) Memorandum of Understanding provided that the United States fully and faithfully complies with its own obligations,” he added.
