There was one awful moment for organisers of the World Indoor Championships when the threat of Yelena Isinbayeva not qualifying for the women's pole vault final loomed after botching two attempts at 4.55m.

The Russian managed to nail her third and final effort to ensure there was no early repeat of her failure at last year's world outdoor championships in Berlin when she failed to register a successful vault.

"I was just a little bit nervous," said Isinbayeva.
