It’s 10:30 on Sunday night in New York, which means that it’s seven o’clock Monday morning in Tehran.

Monday, December 7. Student Day.

In August 1953 Iranian prime minister Mohammed Mossadegh was deposed in a CIA-backed coup. Four months later, US vice president Richard Nixon paid a diplomatic visit to the Shah of Iran, who had implemented Mossadegh’s removal from office. On 16 Azar by the Iranian calendar — December 6 — government troops opened fire on Tehran University students demonstrating against Nixon’s visit. Three were killed. Since then, 16 Azar has been commemorated as Student Day in Iran.

As I type this, the sun is rising on the morning of 16 Azar.

Media reports indicate that Iran’s government is doing everything it can to prevent protests from developing today. Campuses have been shuttered. Internet access has been cut. Student leaders have been arrested, as have the mothers of slain demonstrators. Press credentials for foreign media have been revoked.

The sun is rising.

10:00 am Tehran time | Follow the hashtag #16Azar for news of the day, but remember to approach uncorroborated reports with skepticism.

3:30 pm Tehran time | An interesting insight from Iran News Now and the BBC: “We don’t hear ‘Where is my vote?’ anymore. The chants are mostly directed at the regime and its leaders in general.”

3:45 pm Tehran time | Media reports are still fragmentary, but video and photographs coming out of Iran show large-scale demonstrations on university campuses and beyond. Government forces are doing their best to clamp down, but it’s not yet clear how successful they’ve been.

Tuesday | Protests are continuing into a second day. Here’s a good news roundup from the New York Times.
