TEHRAN -- Long-running efforts to revive the international deal to limit Iran's nuclear program are hanging in the balance after Russia's invasion of Ukraine threw up a new hitch.
On Monday, the U.S. State Department said that an agreement on the Joint Comprehensive Plan of Action (JCPOA) was neither imminent nor certain. Russia's ambassador to Iran said he hoped efforts would resume after the Nowruz Persian New Year holiday, which fell on the same day.
