**Iran’s Revolutionary Guards have warned opposition groups not to hold protest rallies as the country marks 30 years since the seizure of the US embassy.**Reformist leaders have urged their supporters to take part in peaceful rallies on 4 November, including losing presidency hopeful Mir-Hossein Mousavi.
A statement, quoted by Irna state news agency, said it would not tolerate any “diversionary and false” slogans.
Elite units of guards helped suppress mass protests after the June elections.
Mr Mousavi challenged President Mahmoud Ahmadinajad in the election and accused hardline forces of tampering with the vote to steal the election.
At least 30 protesters were killed in clashes and thousands were arrested.
Some 200 opposition activists remain behind bars. Three have been sentenced to death.
The Guard called on the Iranian people to exercise vigilance with regard to the likelihood of plots by enemy agents during the traditional anti-US rally on the date its embassy was stormed by revolutionary students.
