A large explosion struck Iran’s capital Tehran on Friday at a square filled with demonstrators, Iranian state television reports.

The explosion hit Ferdowsi Square, just down Enghelab Street from Tehran University, the epicenter of ongoing Quds Day, or Jerusalem Day, demonstrations. The area is home to many government buildings.

Video published by the semiofficial Tasnim news agency shows a plume of gray smoke rising as demonstrators screamed “Death to Israel!” and “Death to America!”

Footage from Ferdowsi Square showed people shouting “God is the greatest!” as smoke rose.

The strike comes as Iranian media published videos showing top members of the country’s theocracy at the demonstration in Tehran, including security official Ali Larijani and Gholamhossein Mohseni Ejehi, the hard-line cleric who heads the country’s judiciary.

The cause of the blast is not immediately known, and there is no immediate comment from the IDF or Iranian authorities.
