The speaker of Iran's parliament hinted in a US radio interview at the possibility of a prisoner swap to free detained Iranian-American journalist Jason Rezaian.
The comments made to National Public Radio were the latest recent clue that a prisoner swap could be on the table, as US authorities seek to free Rezaian -- held in Iran for over a year on espionage charges -- and other US prisoners.
Asked by NPR on Thursday whether he sees a "practical way" that Rezaian and other prisoners could be released, Ali Larijani said: "There are practical ways, of course. For example, there is a number of Iranians in prison here."
He added: "Definitely for matters of this sort, one can come up with solutions. I think your politicians know about those ways."
Larijani made his comments in New York, where he had traveled for a week of meetings at the United Nations, and for roundtable gatherings with business leaders and academics.
NPR raised the Cuba-US prisoner swap that took place in December as relations between those two countries thawed, asking whether a similar deal might be possible for Tehran and Washington.
"That's one way," Larijani told the US radio network, before saying it was ultimately up to Iran's judicial system.
Larijani's brother is head of the Iranian judiciary.
The comments follow reports that Iran's deputy foreign minister Hassan Qashqavi told semi-official Iranian news agencies last week that "an exchange of Jason Rezaian is not on the agenda."
Despite the denial, the statement was seen as hinting at the possibility of a prisoner swap, largely because Qashqavi went on to mention Iranians held in US prisons and that "we hope conditions for their freedom are realized soon."
Rezaian, 39, had served as the Washington Post's bureau chief. He was arrested in July 2014 and faces charges including "espionage, collaboration with hostile governments, gathering classified information and disseminating propaganda against the Islamic republic," according to his lawyer, Leila Ahsan.
On Sunday, Iran's judiciary reportedly sentenced two people to ten years in prison for spying for the United States and Israel, but their names were not released.
