FIFA president Gianni Infantino on Tuesday promised to "continue to support" Iran's preparations for the World Cup as he met the Iranian national team for the first time since the U.S. and Israel launched airstrikes on the country a month ago.

Infantino spoke with Iran's players and soccer federation officials after flying in from Florida to the Turkish coastal resort Antalya where the team played one of its last warmup games for the tournament, which the United States will co-host with Canada and Mexico beginning on June 11.

"FIFA will continue to support the team to ensure the best possible conditions as they prepare for the World Cup," Infantino wrote Tuesday in an Instagram post sent after he left Turkey.

As the Iranian anthem played before the friendly against Costa Rica, players and officials including coach Amir Ghalenoei and federation vice president Mehdi Mohammad Nabi posed with pictures of children allegedly killed by U.S. and Israeli airstrikes since Feb. 28.

The war has raised doubts about Iran's participation in the World Cup with often conflicting public comments from Iranian government and soccer officials, and U.S. President Donald Trump in the past month.

Iran is due to play two group-stage games in Inglewood, California, and one in Seattle.

Iranian officials suggested moving the team's group stage games to Mexico after Trump discouraged the team from attending the tournament, citing safety concerns.
