Iran has refused to sing its national anthem ahead of its World Cup game against England in an apparent expression of support for anti-government protests in its home country.
Some fans shouted and scoffed during the anthem, while others held signs saying “Woman, Life, Freedom.”
Iranian state television cut its anthem coverage and switched to a previously aired wide shot of the stadium.
Mass protests have been met with fierce repression in recent months.
The death sparked police custody in September of Mahsa Amini, a 22-year-old woman detained by the vice squad for allegedly breaking strict headgear rules.
Human rights activists said more than 400 protesters were killed and 16,800 others arrested in a crackdown by Iranian security forces.
Iranian leaders say the protests are “riots” orchestrated by foreign enemies.
Iranian fans could also be heard chanting ‘Ali Karimi’ in the first half about the former footballer who is one of the Islamic Republic’s most vocal critics and one of the movement’s most popular faces of protest.
Fans could also be heard chanting “Be-Sharaf”, which means dishonourable in Persian. It is adjective protesters have used against security forces in Iran.
Many opponents of the Islamic Republic have blamed the football team for not openly supporting the protests and for meeting President Ebrahim Raisi last week.
Speaking ahead of the game, Iran captain Ehsan Hajsafi said the players were “supporting” those who died.
Manager Carlos Queiroz said his players were “free to protest” against women’s rights in their home countries as long as it “complies with World Cup regulations and is within the spirit of the game”.
Iranian players also hid their national team badges while playing two international warm-up matches in September.
