Today marks the 30 year anniversary of the takeover of the U.S. Embassy in Tehran. A major event in the Islamic revolution back in 1979, Islamic students stormed the embassy and held 52 Americans hostage for over a year. The day has been a huge event for Iran, which now celebrates it as a national holiday.
Despite warnings to stay home, thousands of protestors marched outside the old U.S. Embassy. With shouts of God is great" and "death to America" ringing through the air, the situation quickly turned ugly as police quickly arrived en masse to deal with the crowds.
"I had never seen that many riot police and security personnel," a witness told CNN. "They were brought in by the busloads. As soon as crowds gathered somewhere, riot police were there within minutes."
