North Korea\'s opening women\'s football match of the London Olympics was delayed for more than half-an-hour on Wednesday after an apparent mix-up of national flags. The game failed to start as scheduled at 7:45 pm (1845 GMT) with the official live TV feed showing an empty pitch with the message \"competition delayed\". Pictures posted online showed Hampden Park\'s giant screen beaming an image of a North Korean player next to the South Korean flag.
