Iranian Government - Protestors will be "dealt with in a way that will teach them a lesson."

(CBS) Despite a vicious crackdown by Iran's authorities, CBS News correspondent Mark Phillips reports that there are more ominous signs Tuesday morning that the unrest is continuing.

Iran's official news agency says those arrested in the demonstrations, which have now gone on for a week and a half, will be "dealt with in a way that will teach them a lesson."

According to Iran's state TV, more than 450 people have been arrested and 10 have died in the post-election violence.

The demonstrations may be getting smaller, but those determined enough to continue to take to the streets are paying the price. New amateur video reaching the West via cell-phone and the Internet shows people who have apparently been shot.

Security forces - including the hard-line Revolutionary Guards - have warned that any unauthorized demonstrations will encounter what they called a "revolutionary" response, which clearly involves the use force.

Tehran's streets have been flooded with security personnel in an apparent attempt to intimidate potential demonstrators.

And the political hard line continues as well. A spokesman for Iran's Guardian Council - the body appointed by Iran's supreme leader to oversee elections - has declared that there were no irregularities large enough to warrant calling a new vote. - CBS News Story
