The national football team's elimination from the World Cup has been celebrated by anti-government protesters.
There were videos showing people dancing in the streets in Tehran and other cities.
Many Iranians refused to support the football team because they thought it was a representation of their country.
The players were put under unfair pressure by hostile forces inside and outside Iran, according to state-affiliated media.
The players did not sing the national anthem before the game against England because of the protests.
They sang at the Wales game and against the USA.
Even though there were reports that the team came under intense pressure from the Iranians, some protesters saw that as a betrayal of their cause.
The unrest began 10 weeks ago after the death in custody of a woman who was arrested for violating the rules on covering her hair.
At least 450 people have been killed, including 60 children, in a violent response to what authorities have portrayed as foreign-backed riots. According to reports, more than 18,000 people have been arrested.
A video posted online appeared to show a group of people celebrating the Iranian football team's loss at a square in the country's north-west. They cheer and wave headscarves before the fireworks go off.
