The North Korean women's football walked off the pitch before their opening match at the London Olympics after their images were shown on a screen beside a South Korean flag. The match against Columbia in Glasgow was delayed for more than an hour. After the Olympic organisers apologised, the match started and North Korea won the match by two goals to nil. Meanwhile, a crowd of about 60,000 people turned up at Olympic Stadium in Stratford, east London, for the final rehearsal ahead of the Games' opening ceremony tomorrow.
