UNITED NATIONS (AFP) - UN chief Ban Ki Moon said the offensive anti-Islam Internet video that ignited worldwide protests was "disgraceful and shameful."

Calling freedom of expression and assembly "inalienable" rights, Mr Ban said on Wednesday that they "must be guaranteed and protected when they are used for common justice, common purpose."

"When some people use this freedom of expression to provoke or humiliate some others' values and beliefs, then this cannot be protected in such a way," Mr Ban added, speaking to reporters at the UN headquarters in New York.
