This is the incredible moment hundreds of Iranian students refuse to step on the American and Israeli flags amid anti-government marches in the country and a warning to its leaders from Donald Trump to 'not kill protesters'.
The clip taken at Shaheed Beheshti University on Sunday shows crowds deliberately avoiding walking over the Stars and Stripes and the Star of David before furiously berating those that do.
Ali Khamenei's regime is said to have painted the flags at the main entrance of the university for students to walk over as a sign of disrespect.
In 2016, Iranian professor Sadegh Zibakalam, who has avoided walking on the flags in the past, said: 'It is a sign of disrespect toward that nation. Placing the flag of a country on the ground and stepping on it is an error, a sign of disrespect toward that nation.'
Thousands had on Saturday gathered in front of the gate of the Amirkabir University of Technology near the former US embassy in Tehran to protest the government and Iran's Supreme Leader Ayatollah Ali Khamenei for mistakenly downing a civilian passenger plane.
