US and Iranian men released in prisoner swap

Iran and the United States have carried out a rare exchange of prisoners, despite the tensions between them. It involved Massoud Soleimani, an Iranian scientist arrested in the US after allegedly violating trade sanctions. He was swapped for an American PhD student, Xiyue Wang, who had spent three years of a ten year sentence in prison in Iran for spying - a charge he denied.
