Hatred, chaos and savage beatings in Tehran: Via CNN.com .

EHRAN, Iran (CNN) -- He was surrounded and pleading for them to stop but six men with clubs, batons and metal rods kept battering a young Iranian man with ruthless force. The swing that keeps replaying in my head was the black baton that smashed the man in the skull behind his left ear.

Seconds earlier the man had dared to stand up to the baton wielding men because they had shoved a 14-year-old girl. For his chivalry he got one of the most savage beatings I have ever seen at the hands of four Iranian riot policemen and members of the Baseej, Iran's plain clothed volunteer militia.

"To hell with Iran," he said as he sat beaten and battered along the sidewalk. "This is not my government. This is not my country."

A grown man who watched the beating burst into tears.

This was a glimpse of the ugly aftermath of Iran's presidential elections, which sparked outrage among supporters of candidate Mir Hossein Moussavi.

Moussavi's backers are calling President Mahmoud Ahmadinejad's landslide victory a sham. They're demanding the vote be annulled. The government's response has been a ruthless and violent crackdown.

For eight chaotic hours I saw the two sides clash throughout the streets of Tehran. These were Iranians versus Iranians, but the two sides were worlds apart in appearance, ideology and brute force.

Moussavi's supporters were mostly young 20-something men and women. They were college students, young professionals with degrees demanding social freedom, a better way of life, and better relations with the West.

Two teenage girls carrying bricks had French manicured fingernails and designer sunglasses. The protesters threw objects, burned trash bins, honked their horns and chanted "death to the dictator!"

They were loud, until they heard the roar of the motorcycles.

The motorcycles belonged to two groups of Ahmadinejad supporters: Iran's riot police and the Baseej.
