Tehran terminates 2015 deal under which sanctions were lifted in return for curbs on country's nuclear programme

An international deal with Iran designed to keep the world safe from the spread of atomic weapons has officially ended, with Tehran announcing the termination of the decade-old agreement.

Iran said on Saturday that it was no longer bound by the 2015 agreement, officially known as the Joint Comprehensive Plan of Action (JCPOA), under which international sanctions were lifted in exchange for limitations on Tehran's nuclear programme.
