On Monday, five Americans who were imprisoned in Iran, stepped off a plane in Doha, Qatar. They were freed as part of a prisoner exchange deal between the U.S. and Iran.Despite the happy news, the Biden administration is facing a lot of criticism for this deal, which also gave Iran access to about $6 billion of its oil revenue - money that had been frozen under sanctions targeting the government in Tehran. The deal also comes just a little over a year after the death of a young Kurdish-Iranian woman named Mahsa Amini. Her death sparked the biggest anti-regime protests that Iran had seen in years. NPR's Arezou Rezvani tells us about the legacy of those protests a year later. We also hear reporting from NPR's Michele Kelemen about the U.S.-Iran prisoner swap. Email us at [email protected].
