Iran accuses United States of breaching nuclear deal

Iran believes new sanctions that the United States has imposed on it breach the nuclear deal it agreed in 2015 and has complained to a body that oversees the pact's implementation, a senior politician said on Tuesday.

Under the Joint Comprehensive Plan of Action (JCPOA), signed by the United States, Russia, China and three European powers, Iran curbed its nuclear work in return for the lifting of most sanctions.

However, the U.S. Treasury imposed sanctions on six Iranian firms in late July for their role in the development of a ballistic missile program, after Tehran launched a rocket capable of putting a satellite into orbit.
