Iran's supreme leader issued a warning Friday to protesters who have filled streets since last week's presidential vote: Maintain self-restraint or face a stiff reaction from authorities.
On his Facebook page, opposition leader Mir Houssein Moussavi said he would publish a list of locations for demonstrators to gather in the coming days, and asked supporters to spread the word.
We understand two opposition rallies are scheduled for 7:30am ET - one for Moussavi, another organized by former Pres. Khatami and including Mehdi Karoubi, one of the opposition candidates in last week's election.
