Football Federation of the Islamic Republic of Iran (FFIRI) filed a complaint to Asian Football Confederation (AFC) against Al Hilal after the Saudi Arabian team’s players failed to respect a minute’s silence for the victims of Iranian plane crash.

The silence was planned ahead of the Group D match of the 2018 AFC Champions League between Esteghlal and Al Hilal in Muscat, Oman.

On Sunday, An Iranian commercial plane crashed in a foggy and mountainous southwestern region of the country, killing all 66 people on board.

The Iranian players lined up on the center circle ahead of the match to pay their respects.

But their counterparts from Saudi Arabian team instead walked back to their positions to line up ahead of the game.

Esteghlal defeated Al Hilal 1-0 at the end of the match to remain at top of the group.
