Lead Iranian negotiator Mohammad Bagher Ghalibaf, accused the U.S. of "major MOU violations" after U.S. airstrikes on Tuesday, writes ABC NEWS.

In a statement on social media, Ghalibaf, who also serves as Iran`s Parliament speaker, listed a number of items he claimed as violations of the memorandum of understanding between Iran and the U.S. that temporarily paused hostilities.

Among them: "Violating Iranian adjustments in the Strait"; "Persistent threats of further strikes"; and "Reinstating oil sanctions". The post ended: "The era of bullying and extortion is over. It leads nowhere. We don`t fold". The U.S. said it carried out the retaliatory airstrikes in response to Iranian attacks on commercial vessels traveling through the Strait of Hormuz.
