Iran lashed out at the United States on Saturday for refusing visas to some of its World Cup squad support staff as the players were to leave Türkiye for Mexico.
The row erupted just days before the June 11 start of the 2026 World Cup, which is being jointly hosted by the United States, Mexico and Canada.
The Iranian players, who have been at a training camp in the southern Turkish resort of Antalya since May 18, received their visas late on Friday, Washington's envoy to Türkiye Tom Barrack said on X, hailing the work of the US embassy in Ankara in "processing visas for Iran's national football team".
But Iran's embassy to Türkiye hit back Saturday with a furious response, saying a "large" number of managerial and executive staff and others had been denied visas.
"You have now escalated the deliberate and discriminatory treatment against Iran's national football team to its highest level," the embassy wrote on X.
"FIFA must hold the US accountable for violations of its rules and for the discriminatory treatment of Iran's national football team."
Iran's Football Federation, whose chief Mehdi Taj was reportedly among those denied a visa, also hit out, describing the decision as "political interference in sport in its worst form".
"By extending its hostile behaviour towards the Iranian nation into the field of sport, the ... US government has deprived Iran's national team of.. the opportunity to compete without discrimination," it said, pledging to pursue the matter with FIFA.
Iranian state TV's correspondent in Antalya said the players and their technical staff had received visas, but 15 others on the administrative and management side had not.
It said the matter would be followed up in Mexico.
In April, US Secretary of State Marco Rubio said any problem would not be with the Iranian players but "some of the other people (they) would want to bring with them", suggesting they may have ties to the Revolutionary Guards, a group on the US terror blacklist.
Taj himself is a former Guards member, Iranian media in the diaspora have said.
Team Melli were scheduled to leave Antalya for Mexico on a 3:20 pm (1220 GMT) flight that Taj said earlier this week would include a stopover in Spain before arriving in Mexico early on Sunday.
But Iran's state TV gave a later departure time of 5:30 pm.
The team will be based in the northwestern border city of Tijuana for the duration of the tournament, but all three of their group stage matches are due to be held in the United States.
Iran, who are in Group G, will play New Zealand and Belgium in Los Angeles on June 15 and 21, followed by a game against Egypt in Seattle on June 26.
Ahead of their departure on Saturday, Iran played a final friendly against Mali in Antalya on Thursday which they won 2-0. They played a first match on May 29, beating Gambia 3-1.
