An Iranian woman walks past a mural of a revolver bearing the colours of the US national flag on the wall of the former US embassy in Tehran on November 4, 2009 during a rally marking the storming of the American embassy by Iranian students 30 years ago. Thousands of Iranians staged the noisy anti-US rally in central Tehran as riot police armed with batons and firing teargas moved in as several hundred opposition supporters attempted to stage an anti-government protest.
