The Iranian authorities have issued a warning to the opposition at a mass rally in the capital Tehran.
President Mahmoud Ahmadinejad said opposition groups who worked against the regime would be “banished by the people”.
Supreme Leader Ayatollah Ali Khamenei also gave a warning to past leaders now considered opposition figures.
Tens of thousands gathered at a shrine to mark the death 21 years ago of revolution leader Ayatollah Khomeini.
Ayatollah Khomeini led the 1979 revolution which toppled the US-backed Shah of Iran.
The rally comes just days before the anniversary of last year’s disputed elections.
