TEHRAN, Iran (AP) -- Tens of thousands of Iranians are gathering outside the former U.S. Embassy in Tehran in the biggest anti-American rally in years.

In other years there've been smaller protests marking the anniversary of the 1979 embassy takeover following the Islamic Revolution.
Fifty-two hostages were held 444 days.
