The U.S. and Iran have conducted a prisoner swap in a rare diplomatic breakthrough amid high tensions between Tehran and Washington.
The trade happened Saturday in Zurich, Switzerland. It saw Iranian officials hand over Chinese-American graduate student Xiyue Wang, detained in Tehran since 2016, for scientist Massoud Soleimani, who had faced a federal trial in Georgia.
Iran's foreign minister welcomed the swap, as did U.S. President Donald Trump in a statement from the White House.
Western detainees from the U.S. and elsewhere remain held by Tehran.
They are likely to be used as bargaining chips for future negotiations amid Iran's unraveling nuclear deal with world powers.
