The International Olympic Committee (IOC) Executive Director Gilbert Felli on Saturday said 17 or 18 countries had expressed their interest in hosting future Youth Olympic Games. Amongst them was an African and a Latin American country as well as some cities in the United States, dpa quoted Felli as saying. "There is interest in different places," said Felli, but he would not name the countries or cities. The Austrian city of Innsbruck will be hosting the first winter Youth Olympics in 2012, while the next summer games are set to be held in Nanjing, China, in 2014. Felli said he was "very, very happy" with the current inaugural Youth Olympics in Singapore, which reached the midway mark Saturday and are set to run through August 26. "The organization is going well and the sport competitions are going well," he said, adding that "the spread of the medals is big" with athletes from 60 nations decorated so far.
