Iran's foreign minister said Saturday a detained Princeton graduate student will be exchanged for an Iranian scientist held by the US, marking a potential breakthrough between Tehran and Washington after months of tensions.
Mohammad Javad Zarif made the announcement on Twitter. The trade involves graduate student Xiyue Wang and scientist Massoud Soleimani.
"Glad that Professor Massoud Soleimani and Mr Xiyue Wang will be joining their families shortly," Zarif wrote.
"Many thanks to all engaged, particularly the Swiss government."
President Donald Trump separately acknowledged Wang was free in a statement from the White House, saying he "is returning to the United States."
"We thank our Swiss partners for their assistance in negotiating Mr Wang's release with Iran."
