First Time in the History of Olympiad-Athlete Who doesn’t Represent any Country

A Facebook User Armen Dulyan reports an interesting information about the Olympic Games.
"Today, first time in the history, at the opening of Olympiad in London, will participate an athlete, who doesn’t represent any country... Marathon runner Guor Mariale doesn’t have residence of any country. He is a refugee from Sudan, which was divided into two parts a year ago, and lives in America. Olympic Committee made an unprecedented decision and allowed him to participate as an independent athlete. If he wins, the Olympic anthem will sound. "
