Washington and Iran exchange prisoners

Iran and the U.S. conducted a prisoner exchange Saturday that saw a detained Princeton scholar released for an Iranian scientist held by America, marking a rare diplomatic breakthrough between Tehran and Washington after months of tensions, TIME reports.

In a trade conducted in Zurich, Switzerland, Iranian officials handed over Chinese-American graduate student Xiyue Wang, detained in Tehran since 2016, for scientist Massoud Soleimani, who had faced a federal trial in Georgia.
