For years, staffers of the BBC’s Iranian-language services — and their family members back in Iran — have endured threats to their safety and liberty. Last week the BBC took extraordinary and unprecedented action. It filed a complaint with the United Nation Human Rights Commission on behalf of 152 employees of its Persian-language service against the government of the Islamic Republic, hoping to halt a systematic campaign to silence journalists.

The problem isn’t new. But the broadcaster decided it had to act publicly last November, after Iran’s judiciary moved in August to seize the assets of Persian Service staffers and blocked financial transactions between them and their family members in Iran.

Tony Hall, director general of the BBC, said in a statement after filing the petition that the broadcaster chose to make an appeal to the “United Nations because our own attempts to persuade the Iranian authorities to end their harassment have been completely ignored. In fact, during the past nine years, the collective punishment of BBC Persian Service journalists and their families has worsened.”

Formal and informal threats against domestic journalists working in Iran have always plagued Iran’s media landscape. Newspaper closures, long prison terms for reporters who publish views critical of the regime, and smear campaigns designed to ostracize them from society are all routine.

For foreign journalists working inside the Islamic Republic, the situation is only marginally better. Direct pressure, intimidation and threats of physical violence are common. Some have faced trumped-up legal charges designed to scare them away. Others have been deported. A few of us have done extended time in prison.

What’s new about the recent move against BBC journalists by Iran’s judiciary, though, is that Iran is now attempting to intimidate journalists living and working and a foreign country. This is a new frontier in the Islamic Republic’s audacious attempts to stifle free expression.

Dozens of BBC Persian staff members have been unable to return to Iran to attend the funerals of parents. Others have had their bank accounts frozen. The sister of one reporter was jailed and held in solitary confinement for 17 days. Her captors told her she wouldn’t be released unless her sister stopped working for the broadcaster.

The regime has long struggled — mostly without success — to cut its own citizens’ access to foreign-based media (usually via the Internet and satellite TV). Now it’s focusing instead on going after content providers rather than their content.

The BBC launched its Persian-language television channel in early 2009. It was an immediate hit because it offered continuous content that was more nuanced and less ideologically driven than that of its rivals. Its popularity soared during the weeks following Mahmoud Ahmadinejad’s contested reelection just a few months later.

The Persian Service benefited from a large staff of knowledgeable professionals, many of whom had experience working as journalists in Iran. Free to write and say what they liked, they were able to provide some of the most in-depth, insightful and accurate reporting on Iran, making the Persian Service the go-to source for Persian speakers who sought more objective reporting on their homeland.

Iranian state media face harsh censorship of their coverage on domestic issues, while their reporting on world issues tends to follow the dictates of the regime. Many of the media outlets based abroad are funded by self-professed supporters of regime change.

The BBC’s move is unprecedented — and long overdue. Aside from pushing back against the mistreatment of its staff, the BBC is casting needed light on how the Tehran regime has been able to influence global media coverage of itself.

“This is not just about the BBC — we are not the only media organization to have been harassed or forced to compromise when dealing with Iran,” Hall said in his statement. “In truth, this story is much wider: it is a story about fundamental human rights. We are now asking the community of nations at the UN to support the BBC and uphold the right to freedom of expression.”

Some news directors have accepted the realities that, to maintain a presence in Iran, they must accept a range of unsavory compromises. This can include being compelled to employ state informants even when their double allegiances are openly known.

News executives have been struggling with such pressures for years. Now the BBC should be applauded for revealing what Jamie Angus, director of the BBC World Service, calls Iran’s “pattern of behavior to stifle the work of independent media organizations.”

A ruling from the U.N.’s human rights watchdog would send an important message to Tehran that the world is watching.

“As our attempts to engage Iran privately have been fruitless, we were forced to take more public action,” Angus says. “We believe that, as a witness to the human rights council, pressure by its peers is a useful way of raising the political costs for Iran.”
