Iran freed an American held prisoner for the past three years, the White House said Saturday, while Iran said the U.S. was freeing an Iranian scientist held in America in return.
"After more than three years of being held prisoner in Iran, Xiyue Wang is returning to the United States," the White House said in a statement Saturday morning. "A Princeton University graduate student, Mr. Wang had been held under the pretense of espionage since August 2016."
