When Tunisia takes the field in Kansas City on 25 June, one of its most devoted supporters will be missing from the stands.

Mohamed Sadok Fradi has followed the Tunisian national team to the last two World Cups, but this year his journey will end in Mexico because of US visa requirements.

Fradi, a football enthusiast who sees the World Cup as a way of bringing people together, says the restrictions are not only absurd but contrary to the spirit of the tournament itself.

"I didn't apply [for a US visa] because I don't accept that football supporters need to go through all this pain," he told Middle East Eye.

"I believe a football supporter should buy his ticket, take his flag and go support his team."
