Teheran hospitals report 19 killed in clashes between supporters of reformist presidential candidate Mir Hossein Mousavi and security forces. An unverified number of killed comes to 150, according to CNN. Social network film clips on the Internet show Iranian police shooting protestors, clubbing them, and attempting to disperse the crowds with tear gas and water cannons. It appears that some of the protestors are within the police force.
The demonstrators are protesting what they claim are election frauds in the presidential race in which incumbent President Mahmoud Ahmadinejad won by a landslide. Iran's Supreme Leader, Ayatollah Ali Khamenei approved the election results on Friday and warned against continued protests. Nonetheless, thousands of protestors took to the streets on Saturday. Some of the demonstrators called out "Death to Khamenei."
