Opposition leader Mir Hossein Mousavi said Iran was in "serious crisis" and called for the immediate release of supporters arrested after the June presidential vote, an opposition website reported on Friday.

"Arresting or killing Mousavi, (another opposition leader Mehdi) Karoubi ... will not calm the situation. I am not afraid to die for people's demands ... Iran is in serious crisis ... Harsh remarks ... will create internal uprising ... the election law should be changed ... political prisoners should be freed,"
