Iranians numbering in the hundreds of thousands rallied Friday to protest against the United States with resounding "Death to America" chants following President Donald Trump's warning that the Islamic Republican was "on notice."
Protestors swore allegiance to Iran's religious elite in response to a call from Supreme Leader Ayatollah Ali Khamenei that Tehran is not shaken by U.S. "threats," Reuters reported.
Hundreds of military personnel and police joined demonstrators who marched toward Tehran's Freedom Square to mark the anniversary of the 1979 Islamic Revolution that led to the overthrow of the U.S.-backed shah.
Marchers stomped on pictures of Trump and carried banners that read, "Thanks Mr. Trump for showing the real face of America."
Trump last week slapped additional sanctions on Iran in response to a Jan. 29 missile test.
"Some inexperienced figures in the region and America are threatening Iran ... They should know that the language of threats has never worked with Iran," President Hassan Rouhani told the crowd at Freedom Square.
"Our nation is vigilant and will make those threatening Iran regret it ... They should learn to respect Iran and Iranians ... We will strongly confront any war-mongering policies," he continued.
