Tens of thousands of Iranians flocked to the streets of Tehran Wednesday to join the funeral processions of president Ebrahim Raisi and his entourage, who died in a helicopter crash on Sunday.

In the center of the city, people holding portraits of Raisi gathered in and around the University of Tehran, where Iran's Supreme Leader Ayatollah Ali Khamenei is due to lead prayers for Raisi and his companions, including foreign minister Hossein Amir-Abdollahian.
