Tens of thousands of Iranians poured onto the streets of Tehran on Tuesday (February 11) morning to commemorate the 41st anniversary of the Islamic revolution,
against a backdrop of escalating tensions with the United States.
Many directing their anger towards U.S. President Donald Trump.
Relations remain particularly strained between the countries after a U.S. drone strike killed top Iranian military commander Qassem Soleimani in Baghdad in January.
Iran quickly retaliated with a missile attack against a U.S. base in Iraq days later.
Speaking to the crowd gathered by Tehran's Azadi Tower, Iranian President Hassan Rouhani said the U.S.' agenda for his country was to reverse Iran's 41 years as an Islamic republic.
Rouhani also said Trump's administration lied about the reasons it targeted Soleimani.
