U2 rubbish 'false gig' reports

U2 have rubbished reports they are to embark on a series of live shows later this year, after false advertisements for the dates appeared in the British press.

They played the final gig of their Vertigo world tour in Hawaii in 2006, and are planning to spend 2007 working on new material - but the band has been targeted by pranksters offering tickets to non-existent live concerts.
