3 week milestone in hunt for maddy

Today marks three weeks since four-year-old Madeleine McCann was snatched from her bed - her parents are clinging to the hope that she is still alive and well.Gerry and Kate McCann, both 38, have spent the past 21 days waiting for news of their daughter's whereabouts.Police in the Algarve holiday resort of Praia de Luz have re-questioned two people over Madeleine's disappearance.But with no news on their daughter, the McCanns are now thought to be planning a European tour in a bid to spread their daughter's image across the continent in the hope that she will be spotted and rescued.Today they are expected to begin planning visits to several countries to make personal appeals.A spokesman for the McCanns said that discussions regarding the tour would begin in earnest over the next few days.Backed by an army of friends and family in Portugal and Britain, the campaign has attracted the attention of at least 115 million web users.Yesterday, they were showered with kisses and hugs as they left Portugal's holiest site in the town of Fatima before praying privately for almost an hour in a separate chapel.:: Later today in London there will be a large-scale projection onto Marble Arch of a new yellow ribbon symbol, as part of the rebranding of the Missing People charity.The charity, formerly the National Missing Persons Helpline, is officially relaunching tomorrow, on International Missing Children's Day.
