The IOC has cleared a marathon runner born in what is now South Sudan to compete under the Olympic flag at the London Olympics.

The IOC executive board agreed yesterday to allow U.S.-based Guor Marial — a former refugee — to take part as an independent athlete.

"The voice of South Sudan has been heard," Marial told The Associated Press. "The South Sudan has finally got a spot in the world community. Even though I will not carry their flag in this Olympic Games, the country itself is there. The dream has come true. The hope of South Sudan is alive."

Marial has no passport and is not represented by a national Olympic committee. South Sudan gained independence last year after breaking away from Sudan but doesn't yet have a recognized Olympic body.

Marial moved to the United States as a refugee when he was a child and even though he has permanent residence in the U.S., he isn't yet an American citizen.

That meant he was unable to compete for the United States, South Sudan or Sudan, the IOC said, despite qualifying for the Olympics last year.

IOC spokesman Mark Adams said it was the first case of its kind for the Olympics.

When he was 8 years old, Marial escaped child slavery in a labour camp in Sudan. He is now 28 and lives in Flagstaff, Arizona — where he was preparing for training when he heard he was allowed to go to the Olympics.

"I was getting ready to go for a run. Wow. This is so exciting," he said. "It's hard to describe. I'm speechless. The body temperature is up. I have to train like an Olympian now."
