Iranian Foreign Minister Mohammad Javad Zarif calls for the release of all Iranian hostages, EDNews.net reports citing Mehr News.

"Pleased that Dr. Majid Taheri and Mr. White will soon be joining their families," Zarif wrote on his Twitter account on Thursday.

"Prof. Sirous Asgari was happily reunited with his family on Weds. This can happen for all prisoners,” he added.

“No need for cherry picking. Iranian hostages held in—and on behalf of—the US should come home,” the Iranian foreign minister noted.

Noting that, Tehran announced on Thursday the release of a US citizen, Michael White, who had been imprisoned on security charges in Iran.

He added that "simultaneous with White's release, Majid Taheri, an Iranian scientist who was imprisoned in the United States for false reasons, was released too."

Majid Taheri was sentenced to 16 months in prison for charges of circumventing unilateral anti-Iranian sanctions.

On Wednesday, Iranian scientist Sirous Asgari, a professor of material sciences at Iran’s Sharif University of Technology, also returned home after spending about three years in detention in the US on trumped-up charges of fraud and theft of information relating to his work with a university in Ohio.
