DUBAI —Iran has detained an Australian-based academic on charges of trying to “infiltrate” Iranian institutions, according to official media.

Meimanat Hosseini-Chavoshi was detained as she was leaving Iran, the state news agency IRNA said.

Hosseini-Chavoshi, a population expert, is affiliated with the Melbourne School of Population and Global Health, according to the University of Melbourne’s website.

Population control has become a sensitive issue in Iran since Supreme Leader Ali Khamenei issued an edict in 2014 calling for a population increase after decades of state-promoted birth control.

In October, Khamenei called for greater efforts to combat enemy “infiltration” as tensions escalated with the United States after Washington withdrew from a landmark nuclear deal and re-imposed sanctions on Iran.

Asked about reports that several experts advocating population curbs had been arrested, judiciary spokesman Gholamhossein Mohseni Ejei told reporters on Sunday: “One person has been arrested in this regard ... and three or four people are being sought,” the judiciary’s news website Mizan reported.

IRNA said last week there were reports that authorities had detained an Australian-based population expert on charges that she had tried to “infiltrate” state bodies in Iran.

IRNA quoted an attorney as naming the detained woman as Hosseini-Chavoshi, saying that she did not yet have a lawyer.

The agency quoted the hardline daily Kayhan as saying Hosseini-Chavoshi, reported to hold dual Australian and Iranian nationality, was detained by security forces in a drive against “enemy infiltration elements” as she was leaving the country.

“Everyone knows that the enemy is trying to infiltrate state bodies ... and affect decision-making.” Ejei said. “Foreign intelligence agencies are behind many (academic) institutions ... But some individuals working there might not be aware of these intelligence agencies.”

Reuters reported in 2017 that Iran’s Revolutionary Guards had arrested at least 30 dual nationals in recent years, mostly on espionage charges. Among those held is British-Iranian aid worker Nazanin Zaghari-Ratcliffe, a project manager with the Thomson Reuters Foundation. — Reuters
