Iran nuclear deal crisis talks held amid U.S.-Tehran tension

Diplomats from Iran, Germany, France, Britain, China, Russia and the European Union recommitted Sunday to saving Tehran's 2015 nuclear deal after "constructive" talks in Vienna, a senior Iranian official said, according to AP.

Why it matters: The talks come at a time of heightened tension between the West and Iran, after the U.S. withdrew from the deal and hit Tehran with sanctions. Hours before the talks, the U.S. and Israel said they tested a missile defense system in Alaska. The goal is to intercept long-range missiles from Iran, Barak Ravid writes for Axios.

What they're saying: Iranian Deputy Foreign Minister Seyed Abbas Araghchi told reporters after that while not every issue was resolved, those present were "determined to save this deal," per AP.

The big picture: The United Nations' nuclear watchdog confirmed this month that Iran has followed through on its threat to enrich uranium beyond the purity limit set under the 2015 nuclear deal.

• In the past 2 months, Iran or its proxies have allegedly attacked 6 oil tankers, shot down 2 U.S. drones and struck Saudi oil infrastructure, Eurasia Group's Henry Rome notes for Axios Expert Voices.

What's next: There was a general agreement at Sunday's talks to organize a higher-level meeting of foreign ministers soon, though no date had been set, according to AP.
