Anger over a film mocking the Prophet Mohammad doesn't appear to be letting up. Especially outside the U.S. consulate in Pakistan. Protesters tore down a billboard with U.S. and British flags --- ripping it to shreds and eventually setting it on fire.<br/> <br />The crowd hurled rocks and even a fireball at police --- who responded with teargas as they tried to drive the protesters away from compound.<br/> <br />Pakistan's Prime Minister has called for the video which has enraged much of the Muslim world --- to be blocked on youtube.
