BRUSSELS/PARIS—European parties to the 2015 Iran nuclear deal might launch a dispute resolution process this week that might lead to renewed United Nations sanctions on Tehran, European diplomats said.
Iran took a further step back from its commitments to the 2015 pact with six world powers by announcing on Jan. 5 that it would scrap limits on enriching uranium, although it said it would continue to cooperate with the U.N. nuclear watchdog.
