Tonight, January 8, at 9 pm, PBS’s Frontline show will be Forbidden Iran, about the Iranian Islamic government’s reign of terror and brutal suppression of student uprisings.

In July 2003, Canadian journalist Zara Kazemi was beaten to death in an Iranian prison for attempting to report a story that Iran’s hard-line, theocratic government didn’t want told.

In this edition of FRONTLINE/World, Canadian journalist Jane Kokan goes undercover in Iran to pick up the trail where Kazemi left off.

“The story I am after is the story Zara Kazemi died trying to tell,” Kokan says, “the underground student movement that’s taking on the mullahs.”

In “Forbidden Iran” —one of three segments in this edition of PBS’s international newsmagazine—Kokan risks her own safety to piece together evidence of a government-sponsored reign of terror against students calling for democratic reform. Traveling undercover as an archaeologist interested in ancient Iranian ruins, Kokan escapes the constant surveillance of the Iranian authorities to record exclusive interviews with students and activists who have been victims of the regime’s repression.

“Iran is a country violently split in two,” Kokan says. “It’s a harsh fundamentalist Islamic republic, but it’s also a young country: 70 percent of Iranians are under age 30. And they’ve had enough of the mullahs.”
