Thousands of Iranians took to the streets to protest the official result of the vote -- the re-election of hardline President Mahmoud Ahmadinejad . The government said he won by a landslide , but his opponents accused officials of rigging the results . A crackdown by security forces followed , and at least 30 people died in the violence .
