BEIRUT (AP) — The White House says it is "thankful" for the release of a U.S. permanent resident from Iranian custody, but wants to see other Americans who are detained there released as well.

Addressing the return of Nizar Zakka, who has been held in Iran since 2015 on charges of spying, to his native Lebanon, press secretary Sarah Sanders says, "We're thankful for the release of the individual in Iran."

She says "The big question is there's several others and we want to see those people released as well."

She is declining to say whether the U.S. government was involved in securing Zakka's release.
