According to Twitter feeds from inside Iran, protesters are planning a general strike Tuesday in an attempt to cripple the government. No news of the strike is on either Mousavi's Facebook page or website, but it is rumored he will soon throw his support behind the demonstration. (Mousavi is calling for a day of mourning demonstrations on Thursday.) If the strike is on, government and non-government workers would not show up on Tuesday in an attempt to sabotage the economy and government. It's unclear how effective the strike will be since many cell phone networks remain down in Iran, making organizing difficult. The Revolutionary Guards sent a warning out on Monday that they would firmly discipline protesters, and the hundreds who demonstrated Monday were met with tear gas. "The Guards will firmly confront in a revolutionary way rioters and those who violate the law," the statement said.
