Iran’s football federation said the US has removed the ticket quota allocated to Iranian fans for the World Cup, leaving the federation unable to distribute tickets through its official system, Anadolu Agency reports.

The Football Federation of the Islamic Republic of Iran said Tuesday that FIFA regulations and standard procedures allocate 8% of ticket capacity for each match to the federations taking part in the World Cup. This system allows fans from each country to purchase tickets through an official mechanism coordinated with their national federations, Iran’s Tasnim news agency reported.

The federation had already begun selling tickets via its official website for Iran’s matches against New Zealand, Belgium and Egypt after receiving its allocated quota, Tasnim added.

The federation said the quota allocated to the Iranian federation was later removed, making it impossible under current conditions to provide even a single ticket to the national team’s fans through official channels.

Many Iranian football fans had already made plans to attend the tournament based on the previously announced official process, Tasnim reported.
