Hundreds of thousands of Iranians rallied to swear allegiance to the clerical establishment following United States President Donald Trump’s warning that he had put the Islamic Republic “On Notice”.

On the anniversary of Iran’s 1979 Islamic revolution marchers including hundreds of military personnel and policemen headed towards Tehran’s Azadi or freedom square.

They carried “Death to America” banners and effigies of trump, while a military police band played traditional Iranian revolutionary songs.

Supreme leader Ayatollah Ali Khamenei, Iran’s most powerful authority, had called on Iranians to take part in the demonstrations to show Iran was not frightened of American “Threats”.

Marchers carrying Iranian flags and anti-U.S. Banners ridiculed and condemned Trump’s administration recent statements on Iran.

Last week Trump put Iran “On Notice” in reaction after Jan. 29th Iranian missile test and imposed fresh sanctions on individuals and entities.

Iran said it will not halt its missile programme.
