Iranian students protested outside the Swiss embassy in Tehran on Thursday against an anti-Islam film that sparked violent reactions in several Muslim countries and the killing of the U.S. ambassador to Libya.
Additional security forces were deployed around the embassy, which looks after U.S. interests in Iran where Washington has no diplomatic relations, the Fars news agency reported.
Members of one student organization present called on Muslim nations to "cut their relations with the United States and demonstrate their religious values against the colonial system," Fars said.
Protesters expressed support for demonstrators in Libya and Egypt, shouting slogans including "Muslims unite" and "Mohammad is God's prophet," the report said.
Iran's Parliament speaker Ali Larijani said the film, "Innocence of Muslims", excerpts of which have been posted on the Internet, was "abhorrent" and showed that "U.S. politicians' claims of supporting and respecting different cultures are ... a blatant lie," Press TV reported.
