What we know about an Iran deal

After months of war and deadlocked negotiations, President Donald Trump announced Sunday on social media that he’d struck a deal with Iran. According to Trump and Iranian officials, the deal would open the Strait of Hormuz and end fighting on all fronts, including between Israel and the Iran-backed militant group Hezbollah in Lebanon.

What could these dynamics mean for the agreement? NPR correspondents explain what we know about the tentative deal.
