"I do not believe that I am the champion," said Elemeleh Ofek, "it is an amazing experience. At the last World Championship I was the fifth. I trained very hard for two years. It's a great feeling".
"It was close ...," laughed a happy Elfutina Stefania. "I'm happy, but it was hard to beat the competitor from Hong Kong and the UK," said the world champion in the girls under 17 division.
