Iran's World Cup campaign has yet to begin, but the tournament's political tensions are already threatening to spill onto the field.

Iranian Sports Minister Ahmad Donyamali warned this week that Iran could stop matches at the 2026 FIFA World Cup if what he described as unauthorized flags are displayed or anti-team slogans are chanted inside stadiums, adding another layer of controversy to one of the tournament's most politically sensitive participants.

The warning comes days before Iran open their Group G campaign against New Zealand in Los Angeles on June 15. They will then face Belgium on June 21 at the same venue before concluding the group stage against Egypt in Seattle on June 26.

Speaking to Iranian media, Donyamali said Iranian officials had formally raised concerns with FIFA regarding potential protests during the team's matches.

"We have informed FIFA that if unofficial flags are brought or slogans against the national team are chanted in the stadiums where Iran plays in the World Cup, the team manager will definitely be responsible for stopping the match," Donyamali said.
