Iran's opposition leader Mirhossein Mousavi said his country was in "serious crisis" and called for the immediate release of supporters detained after the June presidential vote, his website reported on Friday. "Arresting or killing Mousavi, (another reformist leader Mehdi) Karoubi ... will not calm the situation," Mousavi said in a statement published by Kaleme website.
"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," his statement said.
Authorities have detained at least 20 pro-reform figures, including three senior advisers to Mousavi, his brother-in-law and a sister of Iranian Nobel Peace Prize winner Shirin Ebadi.
