Iran's football squad has left for a training camp in Turkey without US visas for players and staff, as the foreign ministry accuses Washington of blocking their entry ahead of the World Cup.

Spokesman Esmail Baghaei called the refusal "a violation," noting that FIFA had assured Iranian officials it would uphold its principles. Federation chief Mehdi Taj confirmed Thursday that no visas had been issued for any squad or staff member.

Football official Mohammad Nabi said Iran would play friendlies against The Gambia and another opponent in Turkey, with a match against Puerto Rico in Arizona scheduled if visas are granted.

Head coach Amir Ghalenoei named a 30-man preliminary squad without star striker Sardar Azmoun, dropped after supporting protesters and criticizing government policies. His property has reportedly been seized by a provincial prosecutor.

Iran prepares for its fourth consecutive World Cup, with all group matches in the US. The IRGC, designated a terrorist organization in the US and Canada, complicates entry. Secretary of State Marco Rubio stated individuals linked to the IRGC would be barred. Federation chairman Mehdi Taj was turned away at Toronto airport two weeks ago.
